I like being taller than my entire family, even though my youngest sibling is 9 years older than me.
I like my Voice (And all the things that came with it).
I like my 'how can you even hear that' Hearing Ability.
I got lucky with the whole genetics thing, so I like my hair.
I like my body's ability to endure.
I like when sometimes my hands are
'cold as ice', and I tap someone on the shoulder with my finger.
I have to agree with TehHank on the metabolism, but only because I'll end up eating/snacking on tripleorsomething the amount someone did casually and scare them.
In fact, I probably have a second stomach hidden somewhere, or a black hole.
Otherwise, it's a pain in the ass. Pills here.
