One of my favourite travel writers Bill Bryson travels around the human body. Loads of facts but very readable in his own inimitable manner. . In his chapter on Cancer he mentions Prostate Cancer and says half of men over 60 and three quarters of men over 70 have Prostate cancer at death without knowing it In fact if all men lived long enough they will all get prostate cancer he writes. At £25 a little dear but you find out how much of the bodies organs works. Just possibly a Penguin Edition exists and may be cheaper. Published 2019.
In the chapter on Skin he says 90% of people in the northern hemisphere are deficient in Vitamin D for much of the year. I seem to remember that in the booklet on Hormone Therapy loss of Calcium may occur from the bones leading to Osteiporosis.. So when I saw a container on Morrisons (probably elsewhere too) shelves containing 120 tablets of Vitamin D plus Calcium I bought some. Helps maintain bones and teeth and Vitamin D contributes to normal absorption and utilisation of Calcium the label says. You pays your money and makes your choice. Every little helps. especially if you don't get outdoors so often.
Linus Pauline (2 Nobel Prizes) maintained that a high daily dose of Vitamin C kept his Prostate Cancer at bay for 20 years but since then some of his theories have largely been discredited. Vit C does not keep colds at bay.
