  • You should probably just assume that your genetic information is already or will be out there at some point. If you want to protect against how it could be used against you, my suggestion would be to change your last name from a genetically-based one to one chosen by you. It isn’t foolproof since the name change is public record, but it creates a firewall that makes it harder.










  • I’m no fan of exercise. But as I imminently approach 40, I’m feeling and seeing its value more and more. The purpose of fitness is not longevity - it is independence and quality of life. Just assume you’re going to live to age 90 either way. Look around at some 80 year olds. Breathing machines, walkers, bed ridden… how do you want to spend your years? Years! Your body will become a torture prison unless you tend to it. Dying is the least of my concerns.


  • I was just thinking about this. Love these videos. Cooling of a solar panel is a good application, as long as it gets cold enough for long enough to re-solidify at night.

    An alcohol/NaCl solution with a stabilizer can make an ice pack that freezes colder than water. That could be used to keep ice cream frozen in an ice chest.

    It would be cool to have recipes for a few different temperatures. There’s a German company Qool Products that sells PCM temperature elements (ice packs), at a variety of temperatures, to store ice cream up to red wine/cellar temp in their ice chest. With some trial and error I guess we could now make our own!
