let's reason a bit:

my hair was falling out fairly consistently during my 3rd and 4th years of teaching, but especially this past year.

my hair stopped falling out while i was in cambodia this summer. it was rather thick, actually.

my hair has commenced it's dissatisfaction with my scalp again, falling at what feels like a more alarming rate than before.

other information we know:
1. i am considerably less stressed this year as a grad student than i was before, though i do spend much of my day thinking about the future (more than last year)
2. there is not nearly the level of emotional duress that i endured while teaching high school.
3. i am drinking a lot less now than before.
4. i am generally very happy, as opposed to much of last year.

...i don't know what's going on!!!
