Unfit

Over the last few months I've been walking to and from office, which takes about 20 minutes each way.  I thought that was good exercise.  But this past week I happened to go to the driving range twice to meet some friends.  I don't have my golf clubs here, so I don't go to those places.  But since I was there with them, they let me make some swings, and man, the following day, after both days, I've been so tired I overslept.

At least I was able to confirm I haven't forgotten how to do my swing.
