50% of all MSN Search Traffic is Health Related

[jjspirko]

Not my claim at all but according to an article at Promotion World called "SEO For MSN" writen by Martin Niidi 50% of all searches on MSN (now Microsoft Search) are related to "health".

The author makes the claim at least twice but gives no source for the claim. You can read the article here,

Can anyone state that this claim is indeed correct or that it is not? Anyone got any "secondary sources" for this claim?

I am not picking on the article but this is a very large claim just wonder what if any fact or supporting material are behind it,
