that "Once a cheater...always a cheater" Do you think that is true of someone as they age? he is getting older, but by golly, he thinks he is 25 again..(He is 61) and he goes like the bunny...He was Always a cheater but has remarried (4th wife) settled down?? He seems to take alot of business trips to Asia for sometimes for 10 days..alone, without wife..Always a cheater??
