The Big Question

Many thanks to Michael (Leddy) for retrieving this lost post.



A question that has exercised my waking hours of late runs as follows:

As we grow older does our brain slow down to accommodate our ageing limbs and hardening arteries or, on the contrary, do our physical movements seize up to keep company with our declining brain?

To put it another way, as Robert Peston is wont to say, if I were to take Adderall would I stand up, sit down and walk more briskly? Or if I were to attend gym classes as something more than an observer, would my brain speed up?

In short, does the brain mimic the body or vice versa?

This is a question that has engaged some of the finest minds for centuries.
