4 is better than none! Mind you, I'm impressed with your running stamina - I can hardly get round the village! I'm like a penguin - awkward and slightly comical on land, but graceful and elegant in the water!!!! ;-)
Of course, the real thing round here is that the land slopes a lot, whereas the water is flat!
Remember to live in the real world as well as social networking. It's a lesson I've learned in the last 2 years which has made me much much happier! Grownups can suffer from the same contraction of attention span and the same selfishness as children!!! This week I had twitter, fb, blipfoto and now google+ friend +Theodora Wayte to stay the night and it was SO MUCH FUN! No reason not to social network, but if that's all your life is based on, then it's terribly terribly sad!
