Oxford University mathematician reveals how to avoid spilling your coffee

I have walked with coffee cups all my life. Coffee is almost my only drink. The only time I've spilled coffee was if someone bumped me or I bumped something. I've been doing it for over 60 years. One must not waste the elixir of life.

Here's a suggestion for Oxford... Only fill the cup half way. Or, rather than cut down on your carrying capacity of vital fluids you can change your natural frequency... learn to walk with a limp :-)
