Study the following information carefully and answer the given questions.

Not more than two people sit together who face the same direction. There are three married couples. Note: Husband and wife do not sit adjacent to each other. The age of the husband is more than his wife’s age. If the age of the husband is an even number then the age of the wife is an odd number and vice-versa. The one who is 49 years old sits second to the right of S. The one who is 43 years old is the spouse of the one whose age is a perfect square of a number. The husband of T sits to the immediate right of the one who is 43 years old. S sits opposite to U who does not sit adjacent to P. S does not sit to the immediate right of P. The one who is 51 years sits second to the left of S. The one who is 43 years old sits second to the right of P. The wife of S is 5 years younger than S. T is 7 years younger than her husband.

How many people sit between T and the one who is the husband of P when counted from the left of T?
