Sex can be great in your seventies - no Viagra needed - and it certainly beats fish and chips.

Even though the vast majority of my work was outside television, the amount of creation and inventing that went into the TV shows was non stop and, unknown to me, a great strain.

I am 5ft 6in and weigh about 11 stone - about a stone overweight, but that's because of my brain.

I am still working on patter and presentation.

When people say to me don't the years go fast I have to be honest and say that whereas I don't realise where they go in the long term, I pack so much into a year it seems to take forever.

I don't get many hecklers now but answering them is an art form in itself.
