Did He Or Did He Not?

 Here is a fascinating story about an Indian chief said to have lived to 137. Of course, the government officials disputed it and estimated that he was between 90 and 100 years old when he died, and his wrinkled look was due to a skin condition. And we just happen to know, that the government is always right and knows what's best for you, don't we???

Chief John Smith also had 8 wives but no biological children, and adopted a son, named Tom Smith; which shows that however healthy you are (and you needed to be very healthy to live even till 100 in those conditions), you still can have this kind of problems. I just wonder whether he had all those wives one after another, or simultaneously?
