I can't get the hang of this. It takes me so long to find the blog that I end up with a new account and a collection of empty blogs. Somehow I got back to this one and with luck I will now try and keep it going.

Our book on seasonal timing is still not quite finished . We are nearly there and it will be out in 2008, but in which season I am not yet sure.

While writing it, I became very involved with what is known as the month of birth effect. Simply, the timing of the month you are born in can have enormous long term effects on you, including some non-trivial issues, such as how long you live.

The differences can be a matter of a few percentage points in a given variable. Not huge, but enough to provide some traction in developing research strategies.

I will write about this next time
