Hyperbaric oxygen therapy reverses hallmarks of Alzheimer’s disease and dementia
If this turns out to be true I wonder if it'd be practical (given the financial resources) to have pressure sealed rooms that you spend a lot of time in at home (e.g. your office). These could be precisely controlled (O2, CO2 levels, pressure, …) and possibly both increase current and future performance. The main problem seems the time needed to exit because an abrupt loss of pressure would be hazardous. But if you have a well-structured day it might work. This could be very interesting for high earning knowledge workers imo.
