I’m sad today because Kate’s gone back to York :-(( I must try to do something useful, though.
Here’s a thought. Could mankind have evolved a susceptibility to the common cold, because of its cancer curing properties? If it can indeed kill cancerous cells, it would make sense that those people more predisposed to catch colds would live longer and therefore be more likely to pass on their genes. This could explain why ithe cold is so difficult to cure.
