I have yet another birthday coming up.

Guess how old I am going to be at the end of September 2010!
Send me a message with your best guess and your postal address – which rhymes – and I will send you the same number of a little surprise as a reward for your effort, and the same number of euros off on your next SmarterScience project.*
Everyone who guesses my age right can claim free editing of one scientific manuscript of up to 6000 words.*
But what will you give me as a birthday present?

SmarterScience is running a special Valentine’s Day Sweet Deal, valid until Valentine’s Day (February 14, 2010).
