I knew Milky was joking cos it is programmed into us
Not to speak for the over 40s but it seems we all have this growing optimism, probably because the world hasn't killed us (surprisingly) and we are therefore stronger for it. Also one of the things about in particular discussing films is it shows that the wonder hasn't gone out of life and you can still be dazzled and amazed by things new and old.
Perhaps it is the one thing the younger people (patronised?) here should pick up on and be cheered by. You don't have to worry about getting older and feeling it means brain death, lack of ambition or the death of childish awe. I have seen some really s..t things in life, had some real rubbish thrown at me but am I cynical and grumpy about it? Well only sometimes.
