Incidentally, the Royal Institution Christmas lectures this year are
about food and the way it works our bodies. Starting Boxing day on
Channel 5 (UK).
Woohoo! I always enjoy those, although ISTR them being on C4?

They were! Channel 4 being a regional transmitter you then had to search the
small print to find out when they were on S4C about a week later. Now they
have moved to another channel which does NOT have national coverage ( and
never intends to ) so I shan't be able to watch them at all - boo hiss
grumble grumble.
