Bicycling is fun and healthy; don't believe in tall tales about it's magical prophylactic powers to ward off disease/illness, or as an ersatz Fountain of Youth.
Not a fountain of youth...
But
Not only can cycling (exercise in general) help ward off disease, but it can absolutely reverse some diseases. Heart disease, T2 Beetus, hypertension...
Take insulin resistance/T2 for example. T2 can be caused by a disfunction of mitochondrial cells.

Z2 exercise can prevent and fix mitochondrial disfunction... and that condition can cascade into all sorts of complications/diseases.
