The episode walks through when it is safe to resume sex, what to do if it isn't, and what to ask your doctor. Sam Cradduck, a gerontologist, said the first step is figuring out what's behind the change. Competence and consent come first, she said.

Dr. Rhea Rogers, a board-certified physician, said one of the biggest misconceptions is treating intimacy and sexuality as interchangeable. They're not. For physical issues like erectile dysfunction, a doctor can often help.

The second half turns to clinical trials, which often leave older adults out. Rogers said to start by asking what the trial is trying to answer. Many people see trials as a last resort, but she said the biggest benefit is access to devices, therapies and other treatments that won't reach everyone else for years. Aging expert Amy O'Rourke said participants should know going in that they might get a placebo.

For couples facing a new diagnosis, the advice is practical. Talk openly, check with a doctor, and don't assume intimacy ends when health changes.

The episode also introduces a 91-year-old world record holder in track and field who is proving that staying active has no age limit.
