i just cant stand the smell that really fat people have. any idea what that could be?... i one hundred percent know for a fact you can be considered fat by most people's standards but be very fit so there's a problem with that statement. I still smoke and makes me sad that i do that to myself i used to be really into running, hiking and cycling but it makes it so hard, not just shortness of breath but i think it fucks up your reward systems as well so you are less motivated. Although obesity is still a huge problem, don't judge a fat person. Also doing too much physical activity like a pro or even top level amateurs is basically bad for your health for many reasons specific to that sport.
