I agree completely....

Here in holland a few days ago a newspaper reported reduced balding effects
from a hairdryer cap which was equipped with several probes that were fed from
a simple 9v battery. This was tested on balding men where one
group was subjected to the haircaps only, while another group the 9v batteries
were indeed hooked up. The balding process promptly stopped in the group of
men that were subjected to the electric DC fields for (if I remember correctly)
about half an hour a week.
Extrapolating a 200v DC field might cause enormous hairgrow on your child :-)!
