Can too much exercise damage your brain?

There is research available that suggests it most certainly can. So how much is enough and how much is too much? "Near infrared spectroscopy (NIRS) has been used to evaluate changes in blood volume and oxygen levels in the brain while people exercise".
"The technique demonstrates that even if you are healthy, there could be limitations to just how hard you can exercise without affecting brain activity and potentially doing more harm than good for your health".
This information comes from
"Yagesh Bhambhani and Rohit Malik of the Faculty of Rehabilitation Medicine, at the University of Alberta, Edmonton, Canada and Swapan Mookerjee of Bloomsburg University, Bloomsburg, Pennsylvania, USA explain how during an incremental exercise test, in which exercise intensity is gradually stepped up to exhaustion, the arterial carbon dioxide pressure (PaCO2) and end tidal carbon dioxide (PETCO2) levels breathed out begin to decline at the respiratory compensation threshold (RCT-GEX). Such a fall off in carbon dioxide levels in the arterial system results in a decrease in blood flow to the brain and alters exercise capacity".

Laziness, of the physical variety, I can relate to that, although when I was young I loved to dance, that's good exercise and until more recent years I would swim regularly.
I must confess I was never tuned into housework and I do agree it would take an awful lot to get me to overexercise, but I think a lot of that goes on in sport and gyms.

Definitely, you are fulfilling all your exercise requirements, have a think of what you do to maintain flexibility though.
