Physicist says tech billionaires wasting time on immortality efforts
Physicist Jim Al-Khalili argues that wealthy individuals seeking eternal life through extreme measures are missing out on their finite existence during the Royal Institution Christmas lectures.

Critique of longevity pursuits
Jim Al-Khalili stated that people spending energy to extend their lives might be ignoring the present moment. He noted that humans exist in the universe for a very short period compared to its total age. The physicist suggested that trying to double this brief window is not necessarily a worthwhile use of life.
Examples of extreme measures
Some ordinary individuals are using unregulated peptide injections and cold plunges to fight aging. In contrast, tech chief executive Bryan Johnson has attempted injecting plasma from his 17-year-old son without seeing benefits. These ultra-rich figures aim for immortality through drastic interventions while normal people try less invasive methods.
