@XxDARKNEXUSxX I have. Sounds like a snake -oil sales pitch when it talks of electrons from the ground. They will pass transmit through leather anyway. not to mention walls you then touch.
However, All my life I have walked barefooted whenever possible - I grew up in Africa and hate shoes for the sake of "fashion" rather than as protection. In fact I'm barefooted right now as I type.

@Fanburger Cholecalciferol is ingested in food, and then your body can photosynthesise it into Vitamin D. In less sunny climates, a dark skin does not photosynthesise well. (A possible explanation of varying racial skin colours.) However, Vitamin D is available from many food sources.

@Fanburger It's one of the many crosses I have to bear - always being correct.
The cross is because I'm continually being persecuted by theists who won't accept that I am right.
