Affecting only older people

Why does Covid-19 only affect older people? But the same is true of Southwark's Healthy Rides programme! Why does it only affect older people? It would never have been like that if Barry Mason had still been in charge. Perhaps it's time for a conspiracy theory: Only 1 person of the 6 people who "liked" the Facebook ride report page for last Saturday's ride, 1 of the 15 people who viewed the page and 3 of the 29 people shown as being FB members actually attended the event! It is not just my rides that are being boycotted, but Southwark Healthy Rides too!
