Hi,sir I'm 19 yrs of age. My height is just 5.2 inches and weight about 47 kg. I play football ever?

You can play football.If you keep striving to be in the NFL you will probaly get there.Thats if your good at football,did you play on your high school team?But than again football is just for fun.I think you mean 5.2 feet not inches or 52 inches.
