Can teenagers do ballroom dancing as beginners?

[Glow-ria love yous:)]

I'm 15 years old and I used to dance from my kindergarden years until 5th grade. I stopped then because schoolwork kept me occupied. Now that I'm older, I'm thinking about just taking dancing classes again. I was thinking about ballroom/tango or hiphop dance classes. Which one should I take? and am I too old to start?
I don't want to do any competitive dancing, I just want to take classes as a hobby and something I can do.
