When it comes to health, some things are in the short-term (e.g., safety when working in the shop, being an aware driver) while much is long-term (e.g., diet, exercise) and requires consistency. Physical activity and exercise have always been part of my life (and relate to my profession) so running, cycling, lifting weights, hiking, etc. are all part of the enjoyment in the short-term that provide benefits in the long-term. Having routine check-ups is key to catching concerns early. Seeing colonoscopy brought up - mine was last week and had another polyp removed. Thankfully benign but, if left, that type of cell growth can become cancerous. So, although two days of liquid diet plus the "prep" wasn't any fun, having the test done proved, once again, to be so important (and no sedation so I was able to watch the screen as the doctor did the removal of the tissue - very interesting).
A story on promoting "no smoking" - when I was a kid, my dad placed an auto magazine on the kitchen table, open to a nice new car. He asked my brother and I if we would like to be able to own a car like that some day. Our family wasn't well-off so the thought of owning a shiny sports car was pretty appealing. With both of us in agreement that we would like to be able to buy a new car like that, my dad proceeded to show how NOT smoking would save us $$ considering the cost of a pack of cigarettes, etc. Neither my brother nor I are or were smokers!! Although health implications are surely there, this approach really was so effective, and quite clever on my dad's part to bring it around to something very tangible.
