Today we’re exploring one of the most ambitious self-experiments in human history.

Entrepreneur Bryan Johnson has spent over $2 million in an attempt to slow - or even stop - the ageing process. From diet and supplements to sleep and skin care, every part of his life is measured, analysed and optimised.
