"Guinan explains a surprising realisation that emerged from their work: 'The sun does not seem like the perfect star for a system where life might arise. Although it is hard to argue with the sun's ‘success' as it so far is the only star known to host a planet with life, our studies indicate that the ideal stars to support planets suitable for life for tens of billions of years may be a smaller slower burning ‘orange dwarf' with a longer lifetime than the sun ― about 20-40 billion years. These stars, also called K stars, are stable stars with a habitable zone that remains in the same place for tens of billions of years. They are 10 times more numerous than the sun, and may provide the best potential habitat for life in the long run'. He continues: 'On the more speculative side we have also found indications that planets like Earth are also not necessarily the best suited for life to thrive. Planets two to three times more massive than the Earth, with a higher gravity, can retain the atmosphere better. They may have a larger liquid iron core giving a stronger magnetic field that protects against the early onslaught of cosmic rays. Furthermore, a larger planet cools more slowly and maintains its magnetic protection. This kind of planet may be more likely to harbour life. I would not trade though ― you can't argue with success'."

***To St. Vincent de Paul thrift store. "It's always cheaper right after you buy" department: They now had XP computers for $55.
This week, the free bread was all "Take and Bake." I don't understand the appeal of bread which you have to finish baking.
I got some green peppers and a red cabbage. Green peppers become "too hot" when they age, and I like that.

"Perhaps your novel begins with Neanderthalers being discovered in the hidden mountains of Louisiana. They have abilities which Homo Sapiens lacks...."

To start with, Louisiana doesn't have mountains, so you don't need to worry.
[The mountains are hidden very, very well.
[Next, you'll be telling me there's something wrong with the ending of the opera Manon Lescaut. (The heroine and her lover die of thirst in the desert which surrounds New Orleans.)
[I was trying for the level of accuracy which I associate with successful writers like Dan Brown.]
From: al_zorra Dreamwidth
It also strikes one that since the current crop of scholars still agree mostly that Neandertals evolved perfectly to be a successful Ice Age species -- WTF are they doing in Louisiana, mountains or not?
[Homo sapiens evolved in Africa, and has adapted to much colder climates. If Homo sapiens had died out, Neanderthals might have adapted to life in considerably warmer climates.]
