I’d bet that if a species had a 100,000 year lifespan, they wouldn’t be real big risk-takers. Would you be doing stuff that can kill you at age 25 or 2500, if you’ve got nearly 100,000 more years of life left? I’m not seeing that as being realistic.
On human terms, yes, they might be very risk adverse and take few chances. On the other hand, maybe they would be born in clutches of 10,000 and become insanely open to risk once they have their millionth kid or so.
