I did when I was your age Matthew, but when your job involves driving, many miles of which are in a HGV you really don't see the attraction anymore.
Yebbut, driving on your own terms without a transport manager hassling you in the face of traffic delays (not to mention idle forklift drivers) is totally different.
At the age of 51, I still go off for a drive in the car quite regularly, especially when the weather is not conducive to pleasant cycling (i.e. the last month!). The freedom of going where I like, in my time scale, is such a contrast to driving for a living. I am fortunate in living in an area where we can still enjoy the benefits of roads with sparse traffic. Sitting in queues of traffic is not my idea of fun.
I still have a motorbike too, which takes things onto a whole new level, as can only be appreciated by fellow bikers! It also does away with the problem of traffic queues.
