Quotes to ponder:

"While washing the dishes, one should only be washing the dishes… The fact that I am standing here and washing is a wondrous reality."

"Stress is one of those things which accumulates, so whenever you start to feel the tension build-up, take the time to do something you love, have a breather, and clear your mind."

"Growing fresh, home-grown fruit and vegetables, and inhaling air while digging, can therefore be hugely beneficial to reducing stress levels."

Dr. Jenny Brockis explores compelling research showing that regular physical activity, especially walking, can improve concentration, academic performance, emotional well-being, and long-term brain health. Drawing on insights from Dr. John Ratey and studies on memory preservation, she makes a persuasive case that even modest weekly exercise can help protect cognitive function and reduce the risk of dementia as we age.

Quotes to ponder:

"Brain shrinkage is normal. 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."
