My conclusion about the best-case scenario for my future is this: Before I die, after a long and happy life, I would like to have my consciousness uploaded into a vast amoeba-like cloud of pure energy that would float through space for all eternity. I would look down benevolently upon the mortals in countless star systems and perhaps even be worshipped as some sort of god-like creator. I realise this is probably a long shot, but a guy needs to have goals!
People are living longer these days. While buying a birthday card recently, I noticed a whole section of cards dedicated to people who have turned 100. When I was younger this would have seemed inconceivable that so many would reach this milestone, but now it's a common enough occurrence that greeting-card companies seem to think they can turn a profit by exploiting this fact.
So I think that middle-age is more of a state of mind than a pre-determined number. I can sense it creeping up on me like a stalker when I find myself feeling self-conscious doing things that I've always enjoyed and wondering if a man of my advancing years would appear dignified to others. Middle age is like a second adolescence with less acne and no sense of expectation for the future.
To try and find a way to traverse these dangerous waters I find it best to consider an example from the Baby Boomer generation. A textbook example of a mid life crisis, I believe, is Bob Dylan.
Nobody captured the Baby Boomer promise of youth more fully than a young Bob Dylan and I don't think any image of Dylan illustrates this promise more fully than the cover of his second album 'The Freewheelin' Bob Dylan':
