Beeing outside for long stretches might sound healthy, but at the end of day gives you skin-cancer. Source of Information: Scar over my eye, where the doctor cut out the summers harvest of pesticide resistant weeds in uv-rays.

Skin cancer is generally much easier to treat though than all the other internal cancers people can get from vitamin D deficiency... Also, something to think about: http://dermatologytimes.modernmedicine.com/dermatology-times... "Researchers at the Queensland Institute of Medical Research (QIMR) have revealed that they are finding more instances of melanoma in office workers than people who work outdoors..."

I might have missed it from just quickly looking at that source, but what do they think is causing this increase of melanoma in office workers?

From other things I've read, probably vitamin D deficiency form lack of sunlight is a factor. Of course, there can be too much of a good thing too...

Intermittent sun exposure has also been blamed rather than frequent to promote tanning.

Lack of exercise and stress from indoor jobs may play a part as well in increased cancer risk in general.
