I actually wanted to be a fire-fighter when I was a kid.One trip to the fire-station, a ride in a firetruck and splashing water with their cool toys and I was sold... Ended up being a doctor instead. I love it and you have a lot more options later on in your career. "We Are The Light At The End Of Your Sorry Little Tunnel"

VonSanta is a very lucky boy...He is going to inherit my beautiful (pink & purple!!!) rig and chute once I get my brand new odyssey home from the states in late february! I want it now!!! "We Are The Light At The End Of Your Sorry Little Tunnel"

Smegging shit weather. I don't mind the cold it's all those bloody clouds and the rain and the wind... Danish winters sucks big time. "We Are The Light At The End Of Your Sorry Little Tunnel"

***Atheism is a religion, with a set of beliefs just like any other...and equally unprovable.*** Atheism is NOT a religion. An atheist is simply someone who as the name states don't believe in the existens of gods. The fact that it is impossible to prove doesn't make it a religion.

Cool. welcome! "We Are The Light At The End Of Your Sorry Little Tunnel"

Spend as much time as humanly possible jumping out of airplanes. Not breaking any bones this year (in any sport) "We Are The Light At The End Of Your Sorry Little Tunnel"

Ain't all skydivers per definition dorks? We spend most of our time and money riding in air-planes just to jump out off them. We aquire a very weird vocabulary as soon as we start jumping (for some reason I've started saying "dude" a lot after becoming a skydiver). We all develop an immense interest in all sort of expensive and technical gadgets. We do something completely useless and meaningless (at least my parents tells me it is) just because it's so bloody fun and we really don't care that other people consider us to be time-and-space wasting bums, because we are happy bums. At least I am! "We Are The Light At The End Of Your Sorry Little Tunnel"

Well, I was at work on a 25-hour shift yesterday when I replied to your post. And I do tend to get quite grumpy when I don't get my sleep . But yes the discussion has been amusing. But I still very much would like to see the facts you've collected on the subject, for the sake of my curiosity. At least I got a few more post so I'm closer to get rid of this irritating newbie-status

Well,this isn't true. Increased pressure in the middle ear will not cause any change to the outer size of the head.If the pressure is to high the ear-drum will burst, air will escape and the preassure will reduce. "We Are The Light At The End Of Your Sorry Little Tunnel"

If you deside to trash me, please do me the curtesey an read what I written. I personaly think that "I am a smegging doctor" is a quite clear statement, but hey what do I know. So here it is loud and clear. Yes I am a doctor!. Well that wasn't very objectiv, but I needed to get it out of my system. Now I'm all nice again. And yes I still would like to get a medical expalantion or indead theory to your claim for the sake of my curiosity, so if anyone has it please speak up. I would very much like to know what kind of study you've been doing on the subject, how it was built, for what purpose and what the result was. I have no doubt what so ever that you are far superior to me in any and all areas of skydiving. I'm not writing this to diss you or piss you of...(well mayby the first couple of lines in this post...), but simply because I disagree with you. And for anyone who is curious my nickname has nothing what so ever to do with my profession. It's the name of the drum-machine of my favorite band The Sisters Of Mercy "We Are The Light At The End Of Your Sorry Little Tunnel"

Dude your loading your chute pretty heavily for your experience level. I'm not gonna tell you what to do. Even though you describe yourself as a safe and responsible skydiver you will make mistakes. And when you do you might just need the extra forgiveness a bigger chute gives you. I talk from experience. I considered me a very safe and sensible skydiver (still do though other may disagree ) But never the less I did something VERY, and I mean VERY, stupid on my jump #70. I walked away with a broken shoulder, but that was pure luck. I was very glad that I choose a bigger canopy (and for the fact that it had rained very heavily for a week so that the ground was nice and soft ) "We Are The Light At The End Of Your Sorry Little Tunnel"

Good luck with it dude! Hope the tests leave you in the clear. Brain surgery is scary. "We Are The Light At The End Of Your Sorry Little Tunnel"

Thank you! "We Are The Light At The End Of Your Sorry Little Tunnel"

Yeah, but those guys where religious . I am a smegging doctor! And I don't claim that any of the articles say "the head doesn't expand". I claim that the skull doesn't expand. The links you posted are about DVT and gas expansion due to the decreased pressure at altitude. This is completely unrelated to your claim that the head expands at altitude. And as for free gas in the blood the cause the expansion I can inform you that most gases in the blood is chemically bound to the forming elements of the blood (e.g hemoglobin) for example 95% of oxygen is bound to hemoglobin, only 5% is physically resolved in the blood. Because of this there will be very little expansion of bloodgas during climb to altitude. It's a totally different matter if we're talking scubadiving where nitrogen is dissolved in the blood. and tissue. this gas will cause expansion during uncontrolled assent. But again that is a totally different matter. What I'm saying, and now it's your turn to study the articles a little closer, is that nothing in the article supports your claim that the head expands at altitude. I've spent 7 years in med school looking at pretty pictures like the one link you sent. So I'm not just sticking with some dumb ass idea I found somewhere in space. And If you look at the pretty picture you will see that the bones of the skull is tightly fixed to each other. Thereby the skull case doesn't expand. As for the soft tissue it consist manly of water and dry substances. And water is a fluid and thereby non-compressible that is a fluid doesn't expand in altitude the same goes for the soft tissues. One of the article reffered to DVT (deep venous thrombosis). this occurs manly in the veins of the leg and pelvis. this causes stagnation of blood in the venous system which may give rise to oedema, that is water in the interstitiel tissue, and a swollen limb. But again this doesn't affect the veins of the head, and doesn't cause the volume of the head to expand. If there indeed is any expansion of the soft tissues of the head during climb this would indeed be very minimal. And don't believe anything you read in a article on the net... the net is full of B.S Feel free to correct me, I haven't researched the subject. What I have written is what I know from my education and knowledge of physiology. But if you do, please add some science and a plausible (and relevant) medical explanation to why the head expands at altitude. "We Are The Light At The End Of Your Sorry Little Tunnel"

Well. It doesn't say that the head expands. It say that air trapped inside cavities in the head (i.e sinuses, middle ear etc.) expands. Since the bony cavities of the skull doesn't expand along with the air, this may cause pain due to increased pressure, BUT the volume of the head will not expand. So I stand by my statement. The head doesn't expand in altitude! "We Are The Light At The End Of Your Sorry Little Tunnel"

I find that very hard to believe. The skull is a fairly rigid structure that doesn't expand unless you crack it (witch really can't be recommended), or are a little baby. That leaves only the soft tissue and that would be very little unless you hammer it into something hard and get a bump of course . I'll stick with the theory that my brothers head is expanding due to an over-dimensioned ego! "We Are The Light At The End Of Your Sorry Little Tunnel"

Sooo cute! "We Are The Light At The End Of Your Sorry Little Tunnel"

Hehehe, those dumb-ass human haven't got a clue. Our new disguise as a cloud will sure fool them all. Hehehehe. Yeah, let's attack! The little green martians "We Are The Light At The End Of Your Sorry Little Tunnel"

I used to play soccer a lot, but when you use 6 days a week on training and matches, you only have one day where you can skydive (that is if your lucky with the weather)...So I dropped soccer. Now I just work all the time so I have money to burn on skydiving! "We Are The Light At The End Of Your Sorry Little Tunnel"

June 14 2048, 71 years old in a horrible accident (38%). Well I am stupid so thats probably true... "We Are The Light At The End Of Your Sorry Little Tunnel"

I totally feel the same way... The weather sucks in Denmark right now so I haven't jumped for 6 weeks (well there has actually been 1 day with blue skies, but of course, had a 25-hour shift at work that day). And to make things even worse my skydiving club has a christmas-party tonight, but I'm stuck here (supposedly) studying for my final exams. Sorry I just get all whinei when I don't get my skydive fix regulary. "We Are The Light At The End Of Your Sorry Little Tunnel"

Congratulations! And it will just keep on gettin' better! "We Are The Light At The End Of Your Sorry Little Tunnel"
