Other hobbies?
Hmm, how many would you like?

On the car front I have a 1974 Vauxhall HP Firenza (nicknamed a 'Droop Snoot') which was the last one made out of 204 and has never been registered. Probably never will be now, thanks to the machinations of the DVLC. When I retire I plan to get it running and haul it round to some shows. I also have a 1976 Sports Hatch, an estate version of the Firenza and even rarer, only 197 or them were made.
Sticking with transport I have a few Moulton bikes, '60s period ones, not the more modern versions. I have a Safari, (the first one sold to the public) a Speedsix, a Deluxe, a Major and two Mini 4s. Not many of these are rideable at the same time

To other forms of modelling, I have an American N scale exhibition layout called Smalltown USA and plans to build a much bigger layout in my loft, but many people say that too........
I make plastic aircraft kits, 1/72 scale military from WWII to modern, and major in converting them to variants the full size manufacturers seem to have missed out on building! I do 1/144 scale airliners as well, and I'm a member of various groups who cater for both of these activities.
I do a lot of MS Flight Simulator flying, both at home on a custom built PC that's prime purpose in life is doing just that, and also on my laptop when I'm working away. I do LOTS of that sadly, so the practical hobbies tends to take a back seat during the working week.
As my wife says, it keeps me off the streets..........
