I bought this for my parents although, ironically, the print is rather small and I'm concerned that they may struggle with it! I started browsing through it myself and was hooked. The book is a complete hotchpotch of ideas and styles. There are quotes from politicians, writers, comedians and actors. One-liners, jokes, anecdotes and more serious advice. There is no over-riding structure, it just seems to ramble on in whichever direction feels good at the time.
It only took a couple of hours to read, so is not great value for money. Some of the advice comes across as a little obvious or patronising and feels a little out of place in what I took to be a humorous coffee table/bathroom book. There are a lot of well-known quotes in here which may again make you feel that you've wasted your money. It seems that the writer has a particular liking for certain comedians as well who are quoted bizarrely often.
Overall though it does take a light-hearted look at the effects of ageing (which it assumes occur in those turning 40, not just over retirement age). So not a bad little stocking filler.
