We all start losing brain volume beginning in our twenties, albeit at a very low rate of 0.2% per year." "If the choice is between taking thirty minutes out of my day to exercise, so that I can keep my brain working the way I want it to for as long as possible or choosing to skip the exercise and just take the risk that memory impairment might hit earlier. I choose to get out there and walk." "Brain scans performed nine years later showed that those who regularly walked between nine to fourteen kilometres a week retained a greater amount of grey matter ie brain cells, than those who walked less."
