Troll Lifespans
Like elves, trolls appear to be effectively immortal, easily living
for hundreds or even thousands of years unless they are killed off by injury
or disease. However, unlike elves, trolls show dramatic signs of aging the
older they get; their hair turns white or silver or gray, troll males grow
immense beards, and trolls of both genders develop an impressive array of
warts and wrinkles.
