Gender X Sex

I learnt something new today. We had a lecture on the effects of gender on pharmacokinetics and Dr Momir Mikov began with a few definitions....

Gender "A person's self-representation as male or female, or how that person is responded to by social institutions based o the individual's gender presentation. Gender is rooted in biology (sex) and shaped by environment and experience."

Sex "The classification of living being, generally as male or female according to their reproductive organs and functions assigned by chromosomal complement."

....and to think that i'd always thought they were the same thing. =P

Will be burning the midnight oil tonight, i think. Pathology tomorrow...not fair...we've got a full 8am to 5pm day with the test at 6.30pm! Okay, i might as well admit it. I'm anxious. =/
