I'm so old that I remember when the TARDIS really WAS a police box and they were on street corners everywhere! Nowadays there are still 2 or 3 in the centre of Edinburgh that work as coffee/sandwich stalls!

I'm so old I remember flying in military aircraft that still had propellers - and let me tell you flying from the UK to Singapore on troop carriers was no joke!

I'm so old I still remember 'old' money - ie pounds, shillings and pence (pre-decimalisation). I am also still more comfortable with British Imperial measurements rather than metric.

I remember when Christmas Day was only a half day holiday for workers in Scotland. Our big celebration was and is Hogmanay.
