Taking a swim less than one hour after eating will give you cramps
The Mayo Clinic says it is perfectly safe to swim after you eat a light meal or snack. The site does recommend taking a break after eating a big meal, not because of cramping, but due to lethargy.

Amazon PayPhrase
Amazon's latest payment technology, PayPhrase, lets customers buy from Amazon and affiliated merchants by using two or more words and a four-digit password. The technology, which was announced last Thursday, accesses information stored in the customer's Amazon account to pay for purchases and to identify the shipping address. Like PayPal, PayPhrase is designed to work on Amazon's own site and on third-party sites that use the payment technology.
Amazon wants PayPhrase to compete directly with eBay's PayPal and Google Checkout.
Analysts worry that the combination of a memorable phrase and a simple four-digit PIN may not be secure enough for financial transactions, even if Amazon promises to freeze an account when the wrong information is entered too many times. More ways to spend money in the airways

Nanotechnology
The term 'nano-technology' was first coined in a paper by Norio Taniguchi at the University of Tokyo, in 1974 and the term 'nanotechnology' by K. Eric Drexler in 1986.
Albert V. Crewe, the University of Chicago physicist who developed the high-resolution electron microscope that captured the first image of an individual atom picture in 1970, passed away last week. The significance of his finding is that the diameter of an atom ranges from about 0.1 to 0.5 nanometers
The term nanometer, abbreviated nm, is derived from the Greek word for midget and nano is a metric prefix and indicates a billionth part. A nanometer is about the width of six bonded carbon atoms, and approximately 40,000 are needed to equal the width of an average human hair. Looking at it another way, 1 inch = 25,400,000 nanometers.
DNA width is 2 nm and common bacteria range from 1,000 to 10,000 nm. A nanometer is the length a man's beard grows in the time it takes him to raise the razor to his face.
