6 planets around the dim, slow burning star TRAPPIST-1, have the temperature to permit [almost better, longer] "everlasting life" in paradise. This distant "sun" will give light for another ~ 10 billion years, unlike our sun, which is already half done., with only ~ 4 to go.
everlasting, overlapping life on our planet: naturally impossible. ---
on planets c-g not proven, but likely to last twice as long so: happy overlapping.
