women in science

I was a little disappointed with the WiS report (Rohini Godbole et al).
Here is one article that I feel, presents the situation better.
Women leave "voluntarily" - they take themselves off the career path not because that is what they wish to do, but because they cannot cope otherwise.
Wake up early, make breakfast, fill water in the kitchen , in the washing machine (there is always water shortage), wake kids up, clean up the boiled-over milk, chuck the burnt toast, make fresh toast, find socks, find misplaced car keys, make packed lunch for 4 people, drop kids at bus stand, clean all the mess you made while running frantically, get ready go for work.
After this, stand in the lab for 10 hours inhaling benzene or whatever- get back before the kids get home, (the time doesn't add up does it?), picking up vegetables for the next day, make dinner, check homework, clean up and then hopefully go to sleep.
Mainly, the time doesn't add up.
Can you be surprised if the woman drops out of research ?
