This is analagous to computer system optimization, where the mantra is
"there's always a bottleneck". You can take a poorly performing system,
analyze it, locate the performance bottleneck and remove it, but in doing so
you'll also reveal the next bottleneck.

So, with longevity I think we need to identify and remove the major
bottlenecks (risky behavior, poor diet, poor physical fitness, poor mental
fitness, etc) before we address the higher-level bottlenecks like telomere
length. What's the point of extending the theoretical upper limit from 150
years to 300 years if nearly everyone is dead before 120?
