There is an explanation. It's BS! Look into it. It has been proven to NOT be fact.
I agree, this 20-whatever grams, (many different weights as it is retold), of lost-weight after death was creating by a single man, without any documentation, and perpetuated for several decades now, right here as we watch even. ;D
It is compelling to believe this sort of thing, I will admit, but so far, has no truth to it what-so-ever. If this were science, it would be a whole new brach. Try to find out where this info comes from, and the piers that have reviewed and reproduced this info, you will not likley find anything except for conflicting and wild claims by people with an agenda.
I am not trying to step on anyones toes, but this is definetly information that at best is highly suspect, and at worst, was originally an outright-lie, (in the 1970's I beleive).
Approach all information skeptically- "exceptional claims require exceptional eveidence".
As we aquire information so much more quickly, we also aquire mis-information more quickly. We must use thick filters. Think about all of the urban-myths that are total crap. Open-mind is very good, but a "container", (as in a mind), without "walls" is just a puddle of water on the counter, not very useful.
How did this get here from magnets interaction with laser-beams? :-/
