Question 132: Interested in TKD

I’m interested in TKD I am thinking about taekwondo for me. I am interested in self defense first and competition second. As you know, people say a lot of things about taekwondo. I don't know what to believe. My questions are:

1. Is it true that ITF forms are the hardest and most acrobatic of all the TKD styles.
2. Is TKD only for truly athletic people; I'm not that athletic?
3. Does the WTF style have as many hand techniques as the ITF?
4. Is the WTF any good for self-defense?
