The old saying that lots of sunshine and fresh air makes us healthy probably has to do with absorbing vitamin D.

Suncreen simply blocks UV rays, not really related to vitamin D absorption. Older people, who probably also spend less time outside, do have more trouble absorbing vitamin D as well.

Between a few minutes/hours outside and added vitamin D in my local milk which I drink a lot I don't feel the need for supplements there..

Btw cool graph
