I read with interest the thread started by Pattayamale on Gaybuttonthai on this topic. Although it does not apply to me personally, it aroused my curiosity as my Pa is over 50 and my both my grandpas are over 70. Besides, things like this are good to know at any age. I did a bit of googling and apparently there has been some debate in Singapore on the efficacy of testing. There's also a new test that's supposed to be more effective than the old one but costs more, naturally. Here are some of the links which I found which I hope will be useful reading to some of you:
