I'm hoping that the wire doesn't have a negative effect on my health, in fact I like to think it may have some life extending properties. If I can get 400+ years of extended life do you think I ought to stock up while its cheap? Thanks for doing the maths. I was thinking that 200years would be good value for money, but almost 400 years makes it easier to justify.
i get 1 coil a week as it lasts well, so could be good for 800 years it's a good day.
