Enhancing biological function
Increase the capacity to move, think, resist infection and recover, with useful function as the measure of success.

Build the capacity to live and recover
This approach starts with what an organism can do. Muscle strength, immune protection, cognitive performance and recovery all have measurable limits. Training, regeneration, cell therapies and replacement technologies offer different ways to restore lost capacity or explore an increase in functional reserve.
What to investigate
Choose outcomes that matter in life: mobility, resistance to infection, independent living and recovery after stress.
Compare gains at rest with performance under load and the ability to return to baseline.
Assess how long an improvement lasts and whether it creates a trade-off in another tissue or function.
Evidence to build on
The LIFE randomised trial studied structured physical activity in older adults at risk of disability. Compared with a health education programme, physical activity reduced major mobility disability, assessed through the ability to walk 400 metres. It provides a concrete example of testing preserved function directly.
What remains unresolved
Preserving mobility is a specific clinical benefit. Claims about whole-body rejuvenation, longer life or capacity beyond the usual range require separate evidence and endpoints.
The next useful experiment
Compare a candidate intervention with an appropriate control using a predefined functional test, recovery time and adverse effects, then follow participants or animals after treatment ends.
Proposed experiments →The wider strategy
The presentation discusses replacement at the level of organs, cells and functions. This approach connects those technologies through a common outcome: the capacity they restore or add.
