NASA is more than manned space travel with lots of unmanned missions to other planets and moons. If space travel causes brain damage, it's more like Elon will have problems.
I really like the site, too. I noticed there's no ads at all, and no subscription. The About link explains the site adequately and briefly, but no mention of the owner. I'm curious of the ownership - it doesn't appear to be a business with any revenue for such a good idea.
Perhaps saving planet earth and kick starting clean alternative energy will be what excites the current or near future generation. After that, outer space exploration will still beckon. I can only hope I'm around to watch.
Since high school cross country in the 1970's, we were told the proper distance running form is rolling heal-to-toe, while for the short distance sprinters the form is to land on toes or the balls of the feet. This could be one of those shockers where something I've learned turns out to be false.
Still, I'm still finding it hard to imagine running, say, ten miles by landing on the front part of the foot and not the heal first. Maybe we humans aren't naturally evolved to run ten mile distances. I give it a try, but I suspect I'll be a heal-to-toe distance runner.
