Most of us have seen the joke which has been on Face Book and in e-mails for a couple of years. It goes something like this:
When a baby is in its 1st year, parents will say he/she is nearly … weeks or months; … When children are in the 1st ten years of life they describe themselves as 7 and a half etc; When one is a teenager, the age is always nearly 16 or 18 or soon I shall be 21; In our twenties we look forward to being 30 and then we worry about nearing 40 and so it goes on until in our 90s we revert to being 92 and a half and then almost 100.
