Scientists in America have found that when fed the blood of young mice, aged mice start behaving more youthfully. In particular, they regain the ability to learn new things quickly.
The scientists have 'explained' (that is to say, they have given an insulting over-simplification to journalists) that 'something in the young mice's blood "turns on" the learning connections in the old mice's brains.' Apparently they are now going to try the same thing with humans.
I am, at the age of 69, learning to play the piano; I find that I learn much more slowly than people 50 or 60 years younger. Perhaps, in future, my younger visitors could bring a jug and scalpel with them?
