chin strap is properly tightened. The chin
strap should be positioned against the
neck, not under the chin. It should be
as tight as possible without hurting or
hindering breathing. See Figure D.
4. Fasten the snap on the free end of the
strap to prevent the strap from trailing in
the air.

Effects on people
According to current
magnetic fields of magnets have no
