A friend of mine, just about 57 years old told me she has to have cataract surgery. It is a complication from a previous surgery she had several years ago to correct a different problem. She decided to get trifocal lenses which led me to ask what on earth these are. She said it corrects near, medium and far vision. Apparently medium vision is a viewing area an arm's length from the face. Have you heard of trifocals?
Yet another friend decided to do a DNA test to trace her ancestry and health. She said it took her a good 2 hours to collect half a test tube's worth of saliva which is required for the test. That was surprising. I wonder if most of us would have that problem?
