Natures Compensation

A fellow was explaining to a Kerryman how Nature sometimes compensates for a person's deficiences. For example', he told him, 'if a man is deaf, he may have keener sight, and if a man is blind, he may have a very keen sense of smell'.
'I think I see what you mean', said the Kerryman, 'I've often noticed that if a man has one short leg, then the other one is always a little bit longer'.
