Yes, same guy. I am not 100% sure about numerations, I am not the author of that picture, but extra weight indeed does make people older Or being slim makes you look younger

Weight cutting is a real problem of UFC. Because in a very light weights, you dont fight your opponent, you mostly fight your body. A fight not between fighters, but between their body and nutritionists. If I was in charge, I would not allow to cut more than, lets say 5kg and gain not more than 2 kg in a period between weigh-ins and a fight. UFC and weight is their curse. They have became so popular, that more and more fighters come, and I think were forced to make so many divisions. Competition is so huge, that those who want a belt, are forced to fight not in their original weight and do legal cheating called weight cutting.

Its so funny when huge guys fight among smaller guys and everyone consider it to be fair. Why dont then older students are not allowed to put make up to look younger and go pass exams instead of their younger brothers and sisters ?
