my mate's name is Ben Schiavi and he's 16, same as me.
yeah about the RSI, it actually came from overpractise on piano and it woulda started about 6 months ago. it might seem a little weird that you can injure yourself so badly playing piano, but i finished 8th grade when i was 13 and have been playing increasingly more difficult pieces since...
and these pieces are EXTREMELY phyiscally demanding (ie, Liszt's etudes) and truth be told, you need to be incredibly careful not to hurt yourself.
my right index finger joint has basically been completely spent from overuse and doctor says that in a few years, it may get better to the point where i can play piano for 15 minutes at a time with an hour break inbetween.
pretty shattering when i had my sights on becoming a concert pianist
