You said "we have evolved and selected" which is not true - we have _been_
acted on selectively by the environment; i.e. we _have been_ selected. Big
difference. To get back to the topic, what we need to understand is how extreme
longevity is (apparently) selected against. I think someone addressed that
ealier, though; talking about reproductive tradeoffs.... I'm just concerned
that not being careful about language can lead us into careless and unclear
thinking.
