Just random thoughts that frequently bubble up into my mind...
- Why not take body parts that are severely damaged, then sever them, treat them, and reattach them? I'm thinking things like poison (venom), disease (gangrene), maybe even crushed bones. Remove them, do horrendous things to them (chemicals, radiation, extensive surgery) that the systems of a full body couldn't tolerate, then reattach them to the body again after the parts are in better condition.
- Why not move to a single calendar system that is (mostly) detached from any religious reference? I advocate R.H.H. (Recorded Human History) as a year-o-meter. Just add 4000 to the current (C.E., or A.D.) year and presto, instant year count that could actually mean something relevant across all cultures. So, today is February 13th, 6008. Every human empire and civilization with recorded information would fit into this time scale without annoying pre-post negative-positive numbering issues.
- Why not warn people to stop buying hamsters for kids? I've had a LOT of pets over the years, and hamsters are definitely the most vicious I've ever had. Get a gerbil instead, people. Besides having much better temperament, they're also desert animals with more efficient metabolism and so are much easier to clean up after.
- Why not build cars with windshields polarized to reduce sun glare? And then add slightly-polarized headbeams at cross-angles so that night driving is not so blinding in head-on view.
- Why not create special legislative committees the same way we create juries, with citizens chosen at random and then approved for fitness, so that difficult issues ineffectively handled by Congress could have legislation drafted by conscientious citizens? The draft would then be passed on to Congress for normal deliberations.
- Why not fund one-way human exploratory missions in space? Some people (me included) would gladly accept a one-way ticket to get off this rock and do something productive with our remaining time.
