Off topic: A funny detail is, that Nordic countries have this unofficial (maybe even official) agreement that in acute medical cases, citizens of other Nordic countries are taken care of for free, basically with no questions asked. No need to show travel insurance or anything, applies to operations, x-rays etc.
when it came to cheaters in sports, they'll do things like dope with epo
and blood bank: inject their own previously extracted, concentrated red blood cells back into themselves before the run/ bike (with the subsequent increase in clot risk, of course)
of course, why can't climbers do this as well?
Actually people eat drugs to prevent and adapt better to HA-sickness. The most common is Acetazolamide (Diamox, Ã-demin where I live). It makes blood more acidic, google for more details.
It works great, I used once to climb 16000 feet in 2 days. The only problem is small side-effects, it changes your taste a lot. Most liquids taste odd or bland, except water. And it also causes odd sensations in your feet and arms, like there's been interruption in your circulation, tingling and loss of feel.
Never call a man a fool. Borrow from him.
