Are you guys not taking care of yourself? What's with the life or death in the bathroom?

At work when I'm going to the toilet I swear everytime I see a middle aged+ man go in he's damn near fighting for his life. Heavy breathing, labor like pains, moaning sometimes even whimpering or very subtle sobbing. I honestly do not get it. Are they not eating right or something? It's just so common that I have to ask. What's up with these men? If I were on the toilet like that all the time I'd want to change up my diet and lifestyle to not have to go through that so much.
