"At my age, the radiation will probably do me good"

Norman Wisdom's quote is a funny way of looking at the inevitability of aging. He is suggesting that, at his age, he is likely to benefit from the impacts of radiation, which is usually viewed as a negative thing. This could be translated as a way of accepting the aging process and the changes that feature it. It might also be seen as a method of looking at the positive side of life, even in the face of something that is normally seen as negative. Wisdom's quote is a tip that, even in the face of misfortune, it is possible to find something positive. It is a tip to search for the silver lining in every scenario, no matter how tough it may appear.
