Tech entrepreneur Bryan Johnson, who's 45, follows a strict behavioural regime every day, convinced it will extend his life by umpteen years (it's not clear how many extra years he reckons he'll have).
He eats lots of vegetables, takes 54 pills every morning, does intensive workouts and undergoes red-light therapy (whatever that is). He looks healthy enough, but will a few extra years really justify this strenuous and time-consuming regime?
At the age of 76 I reckon I've lived quite long enough. I've had a fulfilling life with very few regrets. I've met lots of interesting people, soaked up every type of culture, travelled around the world. I've no desire to hang on till I'm 100 and due to get congratulations from King Charles.
How will this guy know if he's increased his lifespan, anyway? If he lives to 100, how will he know if that's his natural lifespan or his artificially extended one? Lots of people live well into their nineties (as my mum did) without any special attempts to live longer.
And why exactly does he want to live longer? Does he think the extra years will make him happier, or more knowledgeable, or more confident? Or is it just for a rather odd sense of achievement?
Not so long ago people often died in their thirties. Now many of us live three times as long. Surely that's enough? Do we really need to go on and on and on? Isn't that just a tad narcissistic?
