Getting more people to ride

I’m 67 years old. I ride quite a bit and I know it’s made a huge positive impact on my health and will continue to do so for the rest of my life - which is going to be longer and healthier thanks to those two wheels. My biggest pain point is seeing others my age who could also be on this road to health, but aren’t. It saddens me to see people struggling with health issues because they don’t exercise and I want to change that. I just don’t know how to go about it.
