Miss Carnivorous, thanks for the comments. I didn't think anyone but my son in Montana reads this blog. I haven't been blogging much lately. I'm teaching a course in Tactical Missile Design for the first time, and am having to do some preparation. I'll be 70 in July, so I've forgotten some stuff I used to know.

Today I played golf at Lake Arlington. I warmed up with a radar gun measuring my clubhead velocity. My typical swing is only 80-85 mph now. That only puts the ball out 200 yards which is not enough. (Michelle Wie could knock the ball 300 yards when she was 12 years old.) So I tried to see how much clubhead velocity I could generate. By twisting like a pretzel I could get from 95 to 105 mph. I decided I would try that swing while I played today. The results were sort of mixed. I did make three birdies. But the drives only went about 220-230 yards. Better, but still a bit anemic. And some of them made huge left turns so that I had a hard time finding the ball. (This was odd since I usually hit a slice when I swing harder.) But my iron shots went 10-15 yards farther, and were more acurate, hence the birdies (two of them were 12 to 18 inch putts.) I'm going to work more on swinging faster.
