It’s being reported that electro-magnetic fields
can influence life span.
Specifically, low frequency, 3D fields, were
evidently found to extend and shorten the life
spans of fruit flies.
This reminds me a little of Bob Becker’s reports
of regenerating amputated limbs in mammals with
 External control of the Drosophila melanogaster
lifespan by combination of 3D oscillating
low-frequency electric and magnetic fields, Posted
