    I have this medical condition:
    that makes me think
    - now we have to protect our "medium tissues", and
    - we will do it by watching our 99th GirlFriend at the safety stop and
    - extending our shallow stops, because
    - Shirley since it didn't work with "fast tissues" and deep stops,
    - the 2nd time's the charmer.

    @dmaziuk - funny!

    TL;DR. Can anyone tell me what I really need to know from this? I'm hoping it says that women are safer divers and won't get the undeserved hit as often - and because we're awesome, we will take care of our dive buddies so they'll be ok too. Is that what it said? I got lost the first time they used GF before explaining it meant gradient factor ... and didn't recover. Sorry. :wink:

    Sorry. It says more body fat is worse and since women do have that, just evolutionary, it means the gender gap strikes again. OTOH they had 10 male subjects for every female one so that has to even things out, doesn't it?

    I never realized that the menstrual cycle (phase) was an important factor.

    Thank you @dmaziuk - so, as long as I can maintain low body fat (thankfully my husband made some major changes in his diet per her doctors instructions AND he's the cook - so I eat what he cooks now) - and since I'm post menopausal (@johndiver999 ) I'm golden! That's all I needed to know.

    I really did read the abstract and jumped to the conclusion, but was too tired after work to tax my brain. Maybe I'll take another shot at it after my coffee has given me the morning jump-start. :wink:

    Meh. They correlated bubbles with age and body fat but they could not correlate bubbles with DCS. They have 300 recorded DCS cases out of 40,000 studied dives and conclude that existing decompression models do not accurately predict 100% DCS cases.

    In other news, water was recently found to be wet.

    Not entirely. According to posters here the chance of a bend is less than 1:1000, 10000 or 100000. So 0.75% ought to be sobering.

    So I read this and they say that decrease of BMI increases chance of DCS but increase of body fat as well.

    does that mean that muscular mass decreases DCS ?

    Yeah, I was most confused by that part.
    Typo maybe?
