Joseph Pilates Quote

The science of Contrology disproves that prevalent and
all-too-trite saying; 'You're only as old as you feel.' The art
of Contrology proves that the only real guide to your true age lies
not in years or how you THINK you feel but as you ACTUALLY are
as infallibly indicated by the degree of natural and normalflexibility
enjoyed by your spine throughout life.
