As an early 40s person who already experiences some of these problems due to 3 decades of arthritis and worsening hand tremors, I'm also interested in geek projects folks can recommend the asker. Especially if they are things I could also work on with my pre-teen sons.

Couldn't Tyson just move all of us to his home planet prior to the asteroid hitting earth? Or is the environment of his home planet inhospitable to earthlings?

Your claim is not scientifically sound:

"child mortality rate goes up in proportion to number of vaccinations per country."

No it doesn't:

Surfing porn all day does not make one an internet expert.

In my large city, I can only recall once ever hearing of such a raid occurring, and it made the news not just the papers. Maybe the problem is you live in western fukakiddyville, and not that such things happen all the time. Perhaps it's just time to move?

Almost any modern HTML + CSS page? :)

That's nice, but only works in a romanticized version of reality. Almost all of my friends live hundreds of miles away. I don't care for most of my cow-orkers, and have little time available to do much with my friends who live nearby because I have a schedule to maintain with my kids and my friends work different hours than I do. There's a ridiculous number of reasons why for many people it is difficult to actually spend a lot of time hanging out with friends IRL, and probably just as many to justify keeping in touch via social media. For many, it's almost like we're integrating technology into our lives to give us more ways to keep in contact with people who physical world constraints make hard to spend face time with.
