Why risk crossing the road? - you could get hit by a car.

Risk comes down to likelihood of harm. I've had no reason to do serious research into the risks of pregnancy - it's not a condition I intend to be in, ever - so I don't know the risks of FAS. Maybe it's a major issue that has somehow passed me by - if that's the case, I apologise.

I do know, however, that an occasional alcoholic drink does no harm whatsoever to an adult and indeed has certain health benefits.

So why not risk it? "Because everyone else does it this way" is not an informed argument: it's peer pressure.
