It’s amazing how many business transactions we can carry on in the privacy of our own homes, wearing our pajamas if we want to.  We can complete banking and credit card transactions, shop online and buy just about any type of merchandise, and in some places order groceries and have them delivered.  People can buy stock from companies such as Transworld Futures, an online futures broker.   Most people probably didn’t realize twenty years ago what all we would be able to do on the computer in the future.  I know I didn’t!
