I'm 17 and about 6'3" tall. The best thing I can think of about being tall is, I can see over most people at things like sporting events.
The worst, I hit my head on stuff alot.(like low doorways) You'd think I'd be used to ducking by now, but I'm not.
Also, I don't fit well in some cars.
But I do have to say, that I like being tall, although it would be nice if I were a little shorter.
I know exactly what you mean. haha
I'm about 5'10" give or take a quarter inch, and I'm constantly banging my head on things, especially cars. I've shut my head in the hatchback door on my mom's car by accident. I've also been whacked in the face with a lock bolt that was jutting off the corner of a door, and the shelf next to the hallway that leads to my bedroom is perfect shoulder height.
So needless to say being moderately tall is nice, however you tend to run into things a lot more.
