> In 2019, a small study raised the tantalizing prospect that ageing could be reversed. Scientists in California gave 9 men aged 51 to 65 a growth hormone and two diabetes medications for a year. The drugs seemed to rejuvenate the men’s thymus glands and immune function. They also shaved 2.5 years off the men’s biological age, as measured by one of the most talked-about technologies in ageing research: epigenetic clocks. It's also worth nothing that another study shaved "3.2 years" off the "epigenetic clock" simply with lifestyle changes over 2 months.
