(UPDATE) In an unfinished part of his basement, 95-year-old Richard Soller zips around a makeshift track encircling boxes full of medals he's won for track and field and long-distance running.
Without a hint of breathlessness, he says: "I can put in miles down here." Steps away is an expensive leather recliner he bought when he retired from Procter & Gamble with visions of relaxing into old age. He proudly proclaims he's never used it; he's been too busy training for competitions, such as the National Senior Games.
This microscope photo provided by the Mayo Clinic in August 2022 shows senescent myoblast cells. Senescent cells resist apoptosis, or programmed cell death, and characteristically get big and flat, with enlarged nuclei. They release a blend of molecules, some of which can trigger inflammation and harm other cells — and paradoxically also stimulate the growth of malignant cells and fuel cancer, says Mayo Clinic researcher Nathan LeBrasseur.
