Also, I have very bad hand-eye-coordination, so can I still learn?
tennis is so easy and takes only a couple months to get caught up on. i did a class for fun when i was 12 nd its easy
I started tennis in 8th grade. It's not too late. The coaches should help you work on hand-eye by having you do multiple drills.
No. It's not too late, although the better players started younger. On the other hand, it's too early to have a Yahoo Answers account. The rule is that you have to be at least 13 years old. So you are currently in violation of that rule and likely to be suspended.
That's a ridiculous question, as long as you understand what sport is about. Sport is not about winning. Sport is about having fun, striving to improve, practicing life skills. With that mind set, no age is "too old" to start anything. Life is about the journey, not the destination.
