Is there something (either disease or some kind of injury) that would ruin a person's singing voice, but not their speaking voice? My character speaks fine; his voice is a little raspy, but not so much that someone listening to him would wonder why his voice sounds odd...but he can't sing worth crap while his (uhh, this is where it gets a little weird) clone-brother-type-thing can sing quite well. They're essentially the same person, and have the same speaking voice, but one can't sing and the other can. Is there anything that could cause this?
I've googled throat trauma, throat injury, ruining your voice, and variations...mostly it gives me information on throat injury that ruins your speaking voice, and warns not to smoke or eat chocolate because it will ruin your singing voice.
Question the second (and third):
I should know this, and googling "dominant foot" and variations only yields results on how to use your dominant foot to find your dominant eye. -_- My gogglefu is failing hardcore this morning. Anyway: if a person is left-handed, which foot is their dominant foot?
And also: is the dominant foot the one you would use in surfing? In other words, if someone is "natural footed" and puts their left foot forward on the board, does that mean that their left foot is their dominant foot, or does/could it depend on some other factor?
...I hope this all made sense. ._.
