Hygiene and checkup. Always nice to be told "you have the teeth of a 40 year old". All the better to bite you with. As I walked up the stairs I reckoned I'd been ascending there for 65 years, man and boy.

Quite a few emails asking why I go for at least one checkup a year; my Mum is responsible and took me to the dentist when I was 4 or 5 - first teeth - and made me go regularly after that. They still have my Mum's xRays and dental details there going back to the 1920s, almost 100 years. Sam Fox used to say the least attractive thing about a man was "green teeth". Mine are pearly white and in great condition, thank you very much.
