Leslie Kenny was told in her 30s that she had five years to live. Diagnosed simultaneously with lupus, rheumatoid arthritis, and Hashimoto’s thyroiditis — and told to give up her dream of having children — she did what true Betties do: she refused the prognosis, threw everything she had at it, and got to work. Now 60 years old, Leslie reports a biological age of 21. She is autoimmune disease-free. And she naturally conceived a child at 43. Her recovery journey led her to collaborate with University of Oxford scientists and to discover spermidine — a naturally occurring, food-derived longevity compound that was hiding in plain sight. It’s been in our food for millennia, it’s in breast milk, and it’s in every plant on earth. And it addresses 9 of the 12 hallmarks of ageing identified by science as the root causes of why we get older.
