bathe...
once everyday, for non-winter seasons. i often have two for winter

shave...
it really depends. perhaps from 1-2 weeks, because i might be lazy and go out with long pants

brush teeth...
once in the morning, and again at night. sometimes i may end up brushing after a meal

wash face...
every morning, while taking a bath, sometimes at night, or just a splash to keep me awake

comb hair...
in the morning, after bath, before going to bed, and whenever it looks like i do need to do so

clean ears...
i always take the time to swab them after every bath i take
