What's your summer plan?

Arent u like 13? U shouldnt do that much excersice, lifting weights in particular or your body will stop growing or deform or something like that. My summer plans are...none, havent made them yet, but I do think I will get a job or do something else that pays money

Most people say that's just a rumor. I made sure with my uncle (he's a doctor) and he said it was perfectly OK and safe.
