Pretty much everything's been covered by the previous posts, so I won't take up space repeating things. I just want to throw a saying my old boss/friend once told me...

It's not the age; it's the mileage.

There are two perspectives on this. You can either treat ageing like a car (you preserve it's beauty by tedious and constant maintenance and care), or you can treat it like a novel on the shelf (the ones we love most get read and re-read, trading the collection of dust for the wearing down of the spine and page glue).
