Is parkour worth trying?

I really like the art of parkour and freerunning. It looks like a very fun sport that I could do everywhere if I practice. I really don't want to be falling alot, so is it worth giving a shot?
Its awesome man really, also i can guarantee u that u will fall alot.
But man, when u master this sport its freaking awesome man, imagine urself like 1 of those pro's from youtube.
If your afraid of heights though it will be hard.
