Hesiod's Five Ages of Man? More like the Three Ages of Michael Fish.

The Ages of Man are the stages of human existence on the Earth according to Greek mythology. Two classical authors in particular offer accounts of the successive ages of mankind, which tend to progress from an original, long-gone age in which humans enjoyed a nearly divine existence to the current age of the writer, in which humans are beset by innumerable pains and evils. In the two accounts that survive from ancient Greece and Rome, this degradation of the human condition over time is indicated symbolically with metals of successively decreasing value.

My version of the ages of man is somewhat simpler. As I was travelling back from Pau to Biarritz today with our Au Pair Marianne, it struck me that being in your early 30s is really quite different from being in your early 20s. Rather than her unnerving ability to pick up song lyrics and knowing the names of bands I’ve never even heard of, nothing summed it up better than our conversation about the weather. My theory is that the first age of man really does not care about the weather – it just doesn’t enter their consciousness (Maxime and Marianne), the second age of man is particularly interested to see the weather forecast (Sandie), and the third age of man (Dad) muses that, “we are not weather makers but mere weather takers”. As for me? I fear I am rapidly racing towards middle age.
