I did not expect this. And it seems weird, since young people are also more optimistic about their futures. And more likely to want to undergo radical life extension. Plus they haven't suffered the effects of aging (having many loved ones die, illness and pain, etc.).

Didn't predictions for the Singularity follow a similar trend? Older people predicting 30-40 years until the event, and younger predictors being more pessimistic because they're likely to still be alive even if it happens in 60 years?
