50th Wedding Anniversary

Jack and Betty are celebrating their 50th wedding anniversary, when Jack asks his wife, “Betty, have you ever cheated on me?”
Betty replies, “Oh Jack, why would you ask such a question now? You don’t want to ask that question.”
“Yes, Betty, I really want to know. Please.”
“Well, all right. Yes, three times…”
“Three?!? Well, when were they?” he asked.
“Well, Jack, remember when you were 35 years-old and you really wanted to start a business on your own, and no bank would give you a loan? But, then one day the bank president himself came over to the house and signed the loan papers, no questions asked?”
“Oh, Betty, you did that for me? I guess I can’t be too upset about that. Well, when was number 2?”
“Well, Jack, remember when you had that last heart attack and needed that very risky operation that no surgeon was willing to perform? And, remember how Dr. DeBakey came all the way up here, to perform the surgery himself?”
“Betty, you should do such a thing for me, to save my life. To do such a thing, you must truly love me darling. How can I be upset with that?”
“So, all right then, when was number 3?”
“Well, Jack, remember a few years ago, when you really wanted to be president of the golf club and you were 375 votes short?”

Robot Crawls Through Veins to Heal You

A new robot, just one millimeter in diameter, can crawl through your veins to treat arterial blockage or deliver targeted medication.

Developed by researchers from Israel's Technion University, what makes the robot feasible is that it isn't self-propelled, saving size and engineering complication. Instead, the bot takes advantage of a magnetic field from outside the body, meaning that doctors can not only guide but also propel the the vein crawler forward at 9mm/second. And the robot shouldn't run out of power mid-procedure, stalling it in your body as it drifts for your brain.

When the robot needs to park, those little arms can spring out and grab onto vessel walls.

Now researchers are looking at beefing up the bot, adding extra tools and even a camera to the mix. And as scary as a robot-filmed reality show starring my aorta may be, it sounds a lot better than having several layers of flesh peeled away via scalpel.
