Multi-tasking – something to ponder

• A lot of people today think they are “good” at multitasking.

evidence says the same thing. They’re wrong.

• Here’s one way to show you– From Psychology Prof at U. Mich, David E Meyer:– Say the letters A-J out loud quickly. Go.– Say the numbers 1-10 out loud quickly. Go.– Say them both out loud, alternating. A-1, B-2, etc.

Go.

It is very important that you learn about traxoline. Traxoline is a new form of zionter. It is montilled in Ceristanna. The Ceristannians gristerlate large amounts of fevon and then brachter it to quasel traxoline. Traxoline may well be one of our most lukized snezlaus in the future because of our zionter lescelidge.

The Montillation of Traxoline

Some review material that you’ve probably seen before…

1. What is traxoline?
