Another damn thing I have to apologize to my children for.
"Hey - you keep doing that, you're going to end up with hideous knuckles!"
Knuckle-cracking is actually good for you
Source: CNN, By Elizabeth Cohen, Senior Medical Correspondent
For the past 15 years, Tanya Johnson has been driving her boss nuts.
It's not her job skills -- Dr. Robert Szabo says Johnson is an excellent nurse -- but rather her incessant knuckle-cracking that makes him want to strangle her.
"I kept telling her to stop, that it was bad for her," Szabo said.
You'd think Johnson might have listened, given that Szabo is a hand surgeon at the UC Davis Medical Center and former president of the American Society for Surgery of the Hand.
But she just kept right on cracking.
"I told him, 'Prove that it's bad,' " she said.

The idea was simple: Gather a bunch of knuckle-crackers (Johnson among them) and have them do their thing under ultrasound to see what was really going on inside the joint. Then examine the knuckles pre- and post-crack, along with the knuckles of a group of non-crackers, to look for problems, including hand swelling and waning grip strength.
Szabo felt quite sure that the study would prove that his nurse needed to stop cracking her knuckles (and also thereby stop driving him crazy). But that's not the way it turned out.

But you have to go for at least a week. The steady rocking of the ship will help remove the gases of the bursa sacks around the joints.
It's true, I swear. And if it's not true, the cruise will cure whatever else ails you.
How many days till you leave? Or are you back already?
I don't leave until Dec. 23rd, but it's coming up fast. 
unfortunately, they made me get off the ship at the end of the cruise.
but it was fantastic while it lasted.
The BEST news though is my wife has been asking me allllll kinds of questions about different ships and where they go and whatnot. Imma cruise again soon lol.
Caribbean christmas decoration should be different!
we're there on the 2nd. I'll try not to drink all the beer before you get there.
