I know it seems like a strange poll / thread, but the wife and I have been talking abou tthis for weeks. She says from what she sees when she uses the WC is that about 75% of Thai women do not wash their hands at all. 20% rinse their hands under the water faucet without using soap and ONLY 5% actually use soap and water.
I started to notice and I would say that 90% of Thai men do not wash their hands at all, 9% rinse their hands and 15 actually use soap.
We both have been talking that most of these women are cooking food and it is not clean. My wife thinks that is were why diarrhea and sickness is so common in the Thailand.
