There are some very distracting DVDs being passed round the Autosport office at the moment and finally they have landed on my desk. (I've just read that sentence back to myself - and it sounds a bit dodgy... No, not those sort of DVDs!)
They're big doses of Formula 1 nostalgia that, as the new season draws ever closer, have brought it home just how much the sport has changed in my relatively short lifetime.
ESPN Classic began showing the original TV broadcasts of the British Grands Prix of the 1970s last year, and those of us who get the channel (not me) raved about them. It was the first time they had been seen in full since they were aired at the time.
And what a treat they are.
