I'm writing this at 4:10pm on November the 5th in London, England. For those of you from the rest of the world, this is bonfire night - toffee apples, sparklers and fireworks... and schools just finished. So while listening to the irregular gunshot sounds from outside my window, i'm getting hungry. I'm hungry, and there are only so many cups of tea you can drink in a day without turning into a teabag, and yes, Its 4:14pm and i'm writing this instead of working... So my question to you- the design and engineering comunity, is what is the best food / drink / activity / music / work aid for an engineer to get my brain back from the brink of dissaster and actualy achieve something with the rest of the day!?
