Sunbathing, vitamin D and calcium

Warning: this entry reveals my shamefully ripe old age.

After buying calcium-rich milk, I talked with a co-worker about bones, calcium and vitamin D.
He was flabbergasted when I told him that one of the sources of vitamin D is sunbathing, and that when I was child, people extolled the healthy virtues of sunbathing.

Apparently, doctors stopped recommending sunbathing once the food available to all became richer, richer also in vitamin D. So it was not necessary to sunbathe anymore for the vitamin and expose oneself to skin cancer risk in the process.

Or…he faked being flabbergasted (more probable).

I am deaf since birth. I played with big computers which eat punched cards and spew out printouts since age 12. Ever since they became available, I work and play with desktop size computers which eat keyboard keypresses and spew out display pixels. Among other things, I developed software which helped the deaf in Israel use the telephone network, by means of home computers equipped with modems. Several years later, I developed Hebrew localizations for some cellular phones, which helped the deaf in Israel utilize the cellular phone networks. I am interested in entrepreneurship, Science Fiction and making the world more accessible to people with disabilities.
