I heard this second hand. My brother-in-law teaches in a school with some ladies who have weight issues. Read on to understand what "weight issue" really means....
Standing in the copy room one day, two of theses ladies were discussing how their obesity creates personal hygiene challenges...loud enough that the following exchange was clearly heard.
"You know how hard it is to wash under your rolls?" "Yeah." "Sometimes I just can't for a while, but if I don't it starts to smell." (Picks up roll of fat -- apparently known in medical circles as an "apron" -- to demonstrate) "Mmhmmm."
My brother-in-law may never recover from the odor or the visual trauma.
