It doesn’t have to be this way. Unhealthy ageing is a human tragedy, and if governments and health authorities shift their focus from lifespan to healthspan, longevity technology can remedy it. Looking and feeling younger for longer is not the preserve of beauty brands or Silicon Valley billionaires.

The average human lifespan has increased by several decades in the past century, but our healthspan – the years we are in good health – has stayed the same. The solution is to treat unhealthy ageing like any other illness, that is, as a technical problem that can be overcome.
