Katie Couric's Notebook:

Right now, odds are you're worried about all the gifts you still need to buy, the visits from out-of-town guests…and that turkey which won't bake itself.

A website called grandparents.com surveyed baby boomers about their holiday headaches. 85 percent said they're worried about the cost of all the gifts and grub. 30 percent say they are anxious over family feuds and sibling spats at the dinner table. While there may be no place like home for the holidays, 11 percent of hosts wish you'd pick someone else's.

And one study found that holiday stress might be bad for your heart, stating cardiac deaths increase by 33 percent between November and January.

Don't let all that running around...run you into the ground.

Take a moment to sit back, relax and have a cup of holiday cheer…before the holidays are actually here.

That's a page from my notebook.
