Probably just a typo but sunlight produces vitamin D, not vitamin C which is obtained by consuming fruits and vegetables
Due to the part played by cholesterols in vitamin D synthesis exposure to sunlight also affects the amount of LDL and HDL types in the body, possibly helping to keep the ratio in healthy proportion
Sunlight is good for you. In summer around 30 minutes exposure a day to bare arms and face is sufficient to maintain correct vitamin D levels, so only slap on the sunscreen after that time, not before leaving the house
The winter sun is not strong enough to do the work which is why it’s advisable to take vitamin D supplements then
Largely agree about statins, though they’re probably useful in those whose cholesterol types are badly out of balance
