Unless I'm being stupid, which can happen, it doesn't make sense.
Wear and tear, just means general degradation of quality or newness, due to extended usage.
A chair might be lovely when it's new, but after 5 years of wear and tear, it will have scratches and dints in it.
If you wish to lessen the wear and tear upon your own mind and body, you need to take good care of yourself. Sleep well, don't drink too much alcohol, don't smoke, drink enough water, relax.
