There's an interesting article on the BBC about a speaker at the TED conference in Oxford advising delegates that the time has come to unplug and slow down.  While I agree up to a point, I think the trick is to budget one's time wisely - making sure to set aside defined periods for family, friends, and relaxation, for example.  Surely the fast pace of modern life only becomes a problem if you let it consume you?  Email can be a great productivity tool, as long as you don't become subservient to it and remember to take a step back and get on with some real work occasionally.

Everything in moderation...
