Sarah Palin is "scary thin"...

... and she's writing a fitness book. 

Celebrities have got to keep moving, looking for an open niche.

Her tips, by the way, are newly frosted, and her nails appeared to be a shade of silver-blue.

"Tips... newly frosted" apparently refers to the highlights in her hair. Highlights are done in strands, right down to the roots and not on the "tips." If there's a space between the scalp and where the light color begins, that means the highlights are not new. The hair has grown. (I know, because I get lowlights.)

As for the silver-blue fingernails, it seems that Michelle Obama got there first, and Ann Romney got there third. But for some reason, light blue is the fingernail color of choice for political ladies this fall. Do they want to avoid the aggressiveness of classic (but blood-like) red? Or do they like the cyanotic look of impending death?

ADDED: Apparently, "frosted tips" is a hoary trend for men:

Boy band members of ’90s and the early aughts were the biggest proponents of “frosted tips,” but no athlete, actor or bank teller has been immune to this god-awful style and its powers of douchebaggery over the years. Do frosted tips transform someone into a terrible human being, or do terrible human beings opt for frosted tips? Let’s find out.
