If Jersh has indeed lost weight then congratulations for him. I'll rip on Jersh for a lot of dumb shit he does but this won't be one of them. I'm serious, I do genuinely congratulate Jersh assuming he's telling the truth about him taking his health more seriously now (he's in his 30s so how he eats and how active he is will affect his health when he becomes and old man; you're better off taking care of yourself now when you're still young because it becomes a bit too late as you get older).
So while I still think Jersh is a self-absorbed retard, I'll offer my congratulations to him for doing something a lot of people don't have the willpower to do.
