Bill Cosby is coming to my home town. He is doing a live show . Should I go?

The tickets price range are 50 dollars to 100 dollars. I don't know about you, but I think thats waayyyy to expensive. By the way, I'm from Rochester Minnesota. He will be at the Mayo Civic Center. He is 70 years old. Should I buy a ticket or not since he will die pretty soon and this more than likely will be his last show he preforms?
