I’m not touching this

So? Go rest up and get better from cancer. I'm over 300 lbs and it doesn't stop me doing jack shit (asthma, of course, can go fuck itself, but that's another problem...). Hell, I've hiked up the Trinity Alps with no training (don't do that, it's fucking stupid) and didn't even pass out! Seriously, though. Being fat just means you move differently. Plenty of people will still want to bang you, and you can do whatever you want. Don't worry about it. (Also if you ever do altitude hiking train first.)
