Look, I am running out of nice things to say about Miami, so I snapped this photo, which is from a hospital in Miami... to tell you about what you may not know, that "they" sometimes give you a dose of this when you least expect it. What am I talking about? X Ray (or x-Ray)... the stuff that comes out of Superman's eyes when he looks at you:

X radiation (composed of X Rays) is a form of electromagnetic radiation. x-Rays have a wavelength in the range of 0.01 to 10 nanometers, corresponding to frequencies in the range 30 petahertz to 30 exahertz (3×10 raised to power 16th Hz to 3×10 raised to 19th power Hz) and energies in the range 100 eV to 100 keV. When they want to look inside you to see your internal structure, they zap you with somewhere between 10 to 120 keV. Ouch! I have no idea how they can decide how many keV to zap you with. If I were to be laying on that table, I would like to know... and I would wear some lead underwear too! Wonder if they'll let me do that!

This is a state of the art x-Ray unit for medical diagnostic service. It looks very expensive and yes, it's all digital now... No more messy films to deal with. No, it's not for me, thankfully!

Travel & tourism has changed drastically over the past century. At one time, taking a vacation was a luxury reserved for only the wealthiest members of society. Now, taking a vacation is practically a requirement for any working individual. Tourism is now a major part of the economy. In some countries, tourism is actually responsible for most of the gross domestic product.
Tourism competitiveness is an important economic indicator. It is a major element in economic stimulation packages. Tourism is among the largest employers in most countries and also a fast-lane vehicle into the workforce for young people and women. Encouraging travel boosts consumer and business confidence,
If you have ever considered going back for a second degree, travel and tourism should figure into your studies. People have more expendable income now than ever before. It is cheaper and easier to travel now than at any time in history. We're living longer and working harder. Tourism is clearly an industry poised for additional growth. Expect there to be a lot of careers in this expansive field.
