Apart from intermittently worrying about the success of my business, my free time is mainly taken-up by reading (mostly historical fiction), brewing beer (with varying degrees of success), shooting small game with a .22 rifle, practicing field archery (I believe it's know as 3D archery on your side of the Atlantic), perusing the internet, cooking (I also like to prepare dishes from both my medieval and Roman cook books), pestering my wife and generally mooching about the house. After dinner I like to lovingly craft and smoke a joint (or two) containing high-end marijuana.
Simple pleasures.
