Thanks for your visits while I have been away. I will try and catch up with everyone who left comments over the next few days.
Nothing quite like a bit of R&R (rest and relaxation). Stocked up on negative ions to deal to that cold that was hanging on.
Negative ions it seems were first recognised by a monk, Abe Bertholon, around 1789. He recorded the effects on people due to changes in electricity in the air. A century later a couple of scientists Elster and Geitel proved these theories. The existence of ions is recognised and how it happens can be explained. There seems to be agreement on the effects on us, however, a lively debate continues on the benefits of machines that create negative ions for improving our health.
I'll carry on getting mine from a bit of sea air.
