What are all the gender/racial perks?
Characters (both player and NPC) may have different weights depending on their race and sex. See: http://uesp.net/wiki/Skyrim:Races
Note that I am not referring to Carry Weight AKA encumbrance.
All races and sexes have 1 weight, except for the male and female Altmer, male Argonian, and male Khajiit which all have 0.5 weight.
How does the weight of a character affect the game?
