Joint mobility is your secret fountain of youth

 Joint mobility exercise stimulates and circulates the synovial fluid in the bursa, which 'washes' the joint. The joints have no direct blood supply and are nourished by this synovial fluid, which simultaneously removes waste products. Joint salts, or calcium deposits, are dissolved and dispersed with the same gentle, high-repetition movement patterns. Properly learned, joint mobility can restore complete freedom of motion to the ankles, knees, hips, spine, shoulders, neck, elbows, wrists and fingers. It's especially important to keep the spine supple and free and if there were such a thing as a fountain of youth, joint mobility exercises come very close.

Just doing neck, arms and torso rotations for 10-20 reps each works great and it's also a great brief morning routine to get yourself charged up for the day ahead. Also such mobility work is a great warm-up before the workout.
