@talk72000,
Sixty years olds normally do not become pregnant without major medical interventions.
Second keeping secrets is far harder to do then most people assume and I had found that women talk far more then men do to their closes girlfriends who then talk to their husbands and lovers………….
In my single days, I found I never knew the sexual relationships details between my co-workers unless I was having an affair at work myself.
My partner would then cheerfully full me in on who is cheating with whom in great detail and I would always end up being both surprise and shock.
