"Geophysicist SPEAKS OUT on Earth's Magnetic Field VIBRATIONS and their Profound Health Effects!"
Many of the people I interact with here at RP are interested in health issues - like preventing them and managing. For that reason, though it may seem a strange topic, it could be useful to give a listen.

Also, anyone who has an interest in or has worked in any of the fields of geology, health, or physics in the past, and has not stayed updated, might be interested in the current approach to these fields that are connected in a more holistic way than in times past, posted by my favorite geophysicist online (i.e. the only one I know of actually, lol) Someone needs to hire him to teach courses at the college level.
