      Red Dwarfs make up a large majority of stars, 60 to 70 percent of all stars I believe. The fact that we keep finding ways in which they seem less and less plausible for native life to get going has huge implications.

      Especially when alot of the other classes including all the giant and exotic types are at least as unwelcoming. Doesn’t leave us with huge numbers of candidates even before thinking of the planets and system configurations.

      The only kind of planet around these types of stars that seem particularly plausible are the under ground ocean ones, and good luck ever actually detecting that on / in exo planets.

      Red dwarf, population 4: A slacker, a holographic smeg head, a human-like creature evolved from a cat named Frankenstein, and an android that broke it’s programming.

      Perhaps there is life we don’t know of that can survive extreme far-UV. This must be considered.
