The IRS periodically alerts taxpayers to, and maintains a list of, phishing schemes using the IRS name, logo or Web site clone. If you've received an e-mail, phone call or fax claiming to come from the IRS that seemed a little suspicious, you just may find it on this list.
Your chronological age is unchangeable and consistent based on your date of birth. Your biological and mental age are dynamic, because you can influence it. With the Lightwerk mental age test you can find out your current mental age. Your biological age can be determined with different tests. Itâs not the years in your life that count.
Originally, the differences between mental age and chronological age were used to compute the intelligence quotient, or IQ. mental age Ã· Physical age Ã 100 = IQ. No matter what the child's chronological age, if the mental age is the same as the chronological age, then the IQ will equal 100. Modern intelligence tests, including the current Stanford-Binet test, no longer compute scores using the IQ formula.
