I would like 2, but actually I have no time to read anything that isn't connected with my work at the moment. 1, would be nice, but like most people I have to nibble when I'm working, so would not be good for the waistline :$. 3 could be interesting, but possibly highly embarrassing, likewise 4.
What I would really like is a 'good gift' or similar for one of the charities I support. This year at work I have persuaded my team to join with me and we are going to get a gift or two from the charity books, possibly one to do with providing clean water, or a starter pack for a former homeless person getting their own flat, and a goat/chicken/bee or two from Farm Africa instead of buying the usual box of something.
