I can think of one disadvantage to longevity. Generally (and this was even
more true in the past), an individuals' offspring care for him when he's
unable to care for himself. This minor drain on your children's resources
could be enough of a disadvantage to mildly impact their reproductive
rates - hence your "long term" reproductive rate (by which I mean total
number of descendants).
