The Door That Doesn’t Need Insulin
Here is the part that matters more as we age. When a muscle contracts, it pulls glucose out of your blood through a door that does not require insulin to open (an insulin-independent pathway).

A walk after dinner reaches for the one lever that does not age the way the others do.
