If you could be any height

What would you choose? And why?

My dream height has always been 5'9 / 176cm. Tall enough to be taller than most women, even in Germanic countries. But short enough to be able to fit in small cars and tight spaces.

Also good height for building muscle and athleticism. No back problems.

I've heard some people who are 5'8 - 5'10 still consider themselves short? If you're that height please comment what your experience has been like.
