That's what the paper says. Whether you would take that deal depends on your level of risk aversion (which the paper gets into later). As a wise man once said, death is so final. If we lose the game we don't get to play again.

Everyone dies. And if your lifespan is 1400 years, you won't live for nearly 1400 years. OTOH, people with a 1400 year life expectancy are likely to be extremely risk averse in re anything that could conceivably threaten their lives ... and this would have consequences in re blackmail, kidnapping, muggings, capital punishment, and other societal matters.
