Thanks, kimmers. I knew that, but could not have put it so well. Back when I used to have this "problem", albiet not in null/micro gravity, I used tampons only on the last 2 or 3 days, so that I was certain I was finished. Stained knickers are just the pits.
One of the glorious things about menopause is that you can buy clean, white panties and they will stay that way!
Tampons do "draw", hence, Toxic Shock Syndrome if they are used too much or left in too long.
(my god, the things we discuss on Mudcat........any other personal stuff you want to know about? Childbirth and episiotomies for instance? PAP smears? Piles?)
Something that has not been mentioned here is that females who "train" heavily, such as Olympic atheletes, quite often skip menses while in training, and then later have trouble regularizing their cycles. When the body is over stressed, it deletes functions, often to the body's own detriment.
