dude, it's never too late, however there are certain styles you might have trouble with, you might also have more trouble than those who started training young because of the different muscle groups you use, but it shouldn't be too much of a problem:)
perhaps when you are younger your joints are more flexible and the stretching is easier to do
but if you train well and regularly it isn`t a problem, your age ;-)
im 15 and i only started to learn to play guitar XD
