What do old people think?

Do you ever wonder if old people question whether or not they are going to outlive the set of new tires they just bought for their car?  If you're in your 80's chances are you're not putting alot of miles on the old Studebaker so it would probably take years to accumulate the 60,000 miles necessary to wear out the thread of a new tire.  I bought new tires today and it cost me $600.  I can't wait to be old enough to buy my last set of new tires and then cantankerously wait for death.
