A seasonal thought: "sewer abuse". More fat is poured down our drains at Christmas than at any other time of the year. The fat congeals, blocks the drains, and intrepid sewer men need to dig the filthy stuff out. So, the message for our effluent society is Cool it and bin it. Previous generations cooled it and ate it. I can remember as a boy eating "dripping" sandwiches with a lick of Marmite to give the fat flavour. As "dripping" is full of unhealthy saturated fat, you're better off binning it; but in the days of post-war rationing you conserved and ate everything you could. Our local butcher had a rack of dead wild rabbits hanging behind his counter. Rabbit pie was one of my favourite meals.
