My mother and sister both have. Well, a glucose tolerance. I don't know about the oral part.
Then dad went all anti-doctor on us. I never have and most likely never will. I also could die of cance but, you know, I think it's worth it. (<---Joke. Cancer sucks. I shan't belittle it or anything.)
I've played piano for the past ten years. I never mastered guitar -- so I do what with my one hand and I play the actual notes with my other one? Ah, that's not fuckin right...
As it is, I do have to be a bit smug: I once took a Music Theory class with a bunch of guitar and drum players.
The first half of the semester was dedicated to mastering both clefs, musical notation, and keys.
...admittedly, I learned to play piano while I was still very young. The older you get, the harder it is to learn any language.
I took piano lessons for two years. I can't read music worth shit and the only songs I can play are the songs in the book about robots and sailboats.
I taught myself guitar and within one year I could play at least a simplified version of pretty much any song I knew. I understood how the notes worked and everything.
Ukulele was just easier because there's only four strings and the chords are simpler.
Yer, everyone's different, I guess. Piano came naturally to me after a while with my big hands (I have about a ten-key reach, and about an octave when I was younger) -- but I never really 'got' guitar. vOv
XD Yeah... lately I've been working on "Fur Elise", which has some really goofy parts where the notes span octaves within a few seconds. My enormous man hands allow me to finger those parts without too much awkward pain.
It even makes it hard to play guitar because barre chords are fucked and I can't bring my thumb around and mute certain strings. I finally can play a D without awkward strumming though. :D
