I went to school in the 50s and 60s and wasn't the best student but I had excellent teachers. Why I didn't make the highest grades was that the subjects weren't easy and required actual study. It's tragic how under-educated today's youth seem to be but it's obvious my generation is plainly smarter. It's painful to watch the youtube street interviews with people who can't answer the simplest questions.
I'm always searching for incandescent bulbs. I'm a bit old fashioned but I prefer the warm glow. Bring 'em back!
