I do understand the gist of what infinitely repeated games are in that T=$\infty$ ; that is the stage game is played each period for an infinite number of periods.
In his book "Strategy", Watson makes the following claim:
Although such a game may not seem realistic at first (people do not live forever), infinitely repeated games are useful for modeling some real-world situations.
With reference to the part in bold, could you elaborate?
Thanks.
