-459.67F = Absolute Zero

  I found out today I have an MRI coming up on the 28th.

They asked me if I was claustrophobic.

I had to think back 50 years to when I was on a bus with suitcases stacked 2 high in the aisle when you couldn't even stand up to stretch your legs for many hours.

I quickly solved that by asking everyone to have their luggage outside their hotel room doors 1 hour before we were to depart and from that point on, and for the next three months of our tour, I loaded 40 peoples luggage UNDER THE BUS INSTEAD OF IN THE AISLE by myself.

Never had claustrophobia again.

This is how I approach problems and solve them.

Look at the challenges of quitting as things that you can solve simply by changing your mind and doing things differently just for that moment

Doing research on MRI's, I found out that  the magnets the MRI ses must be kept at Absolute Zero to do their work properly.

How does an MRI scan work?

   An MRI scanner can be found in most hospitals and is an important tool to analyze body tissues.

An MRI scanner contains two powerful magnets, which represent the most critical part of the equipment.

The human body is largely made of water molecules, which are comprised of hydrogen and oxygen atoms. At the center of each atom lies an even smaller particle called a proton, which serves as a magnet and is sensitive to any magnetic field.

Normally the water molecules in our bodies are randomly arranged, but upon entering an MRI scanner, the first magnet causes the body's water molecules to align in one direction, either north or south.

The second magnetic field is then turned on and off in a series of quick pulses, causing each hydrogen atom to alter its alignment and then quickly switch back to its original relaxed state when switched off. The magnetic field is created by passing electricity through gradient coils, which also causes the coils to vibrate, resulting in a knocking sound inside the scanner.

Although the patient cannot feel these changes, the scanner can detect them and, in conjunction with a computer, can create a detailed cross-sectional image for the radiologist to interpret.
