Eyes? OK, here's one about eyes.
In 1992 I went to get my driver's license renewed. The gal behind the desk had me read the chart, and frankly, most everything was kind of blury. She, being the comedienne she was, inquired if I wore glasses. I replied No, I do not. To which she came back with, Well sir, if you want to get a driver's license you will. So I did. It was amazing how much better I could see targets, too. Fast forward 18 years. I had to get a California license. Went down to DMV and they did an eye check on me - no problem, was not required to wear glasses. I had to renew in person last August. Went through the same drill about reading the chart. This very nice lady asks if I wear contact lenses. Nope, I replied. To which she responded, My goodness, for a man your age, you have very good eyesight. Well, thanks, I guess.
However, I have found that it is more comfortable to read with some dime store reading glasses than without. I also find computer work to be easier. Was no problem getting used to them.
I know what you mean about Johnson getting more explicit with his writings. Seems like a few friends and myself took to calling his stuff Prairie Porn. I also saw no need for that, his stories were draw enough for me without putting that stuff in it. And yes, you are right about his temperament. He did not take kindly to anyone criticizing his writing. Pretty narrow minded, I thought. The trip I took with him had all the potential to be wonderful, but as it worked out, not so much. I wound up selling a nice rifle that I wish I had back to finance part of the trip. Bad deal. Also a set of 4 chrome wheels and brand new tires, plus an Olds manifold and 3 carburetor intake setup. Not worth it at all.
