Could also be that women are the ones who have to be tougher to make it in life...ya we do. Have the kids, clean the house, do the laundry, shopping, vacuuming, school stuff, christmas stuff, birthday stuff, inlaw stuff, run to the bank, paying the bills, take the dog to the vet, hold down a job, or two, did I mention childbirth in there?
We don't have time to get sick.
