I'm nearly 90, full of aches and pains. Some days don't end soon enough, some go by quickly. I try to keep busy writing or coming out of retirement to occasionally lecture or present a glorified show and tell session. I've become an amateur archaeologist of sorts, walking the river looking for signs of early settlement. I annoy my wife on a regular basis. I'm on a first name basis with most dial a ride drivers.
I sometimes use a cane. Those days are not fun. I have a large number of email friends. And I spend too much time in front of the computer.
