Staying alive has become easier,maybe. Modern materials like gortex, waterproof down and such. But what tech has made it easier to climb?
It has nothing to do with cold weather....its the altitude that will kill you. You are up 30k feet. Man was not meant to survive at that heights. Sherpas are there because they adapted to those highs living their since B.C. However, even they can get fucked.
Things that can fucking kill you on Mt Everest Other Than Freezing:Avalanche
Injury from fall
Ice collapse
Oxygen tank depleted if you use them (most do)
Brain hemorrhage
Mountain sickness
Getting crushed under the serec or crevice
Heart Attack
Suspended upside down for too long
Exhaustion
Drowning (Yes you can drown)
Cerebral Edema (HACE)
Dehydration
Cerebral apoplexy
Stroke
HAPE (High Altitude Puluminary Edema)
And you can still freeze to death. You can spend 50k to attempt it but dying is absolutely free with your purchase. Only fucktards climb mountains
