a. those charges are somehow loaded on advanced technology, 20 years down the road

im 17. ill see nanotechnology and gene therapy.
but if your older; dont dispair!!! science and the laws os mathematics MAY allow for life after death. just take vitamins and hope u live long enough to see new technology
