Turns out, some people over 60 have 'youthful' immune systems thanks to special stem-like T cells. These super cells help keep you strong and spry, but here’s the catch: they also make you more likely to get autoimmune diseases. Scientists are now working on tests to spot these cells early. So, living longer might come with a wild immune system ride! Would you risk it for a shot at 100 candles? #Health #BodyHealth #Longevity
