Scientists accidentally kill world's oldest animal at age 507. The oldest animal ever known lived from 1499 until the day researchers cracked its shell open, killing it in the process.
For example, there is a federal law (and similar laws in every state) allowing consumers to cancel contracts made with a door-to-door salesperson within three days of signing. You might use that law after hastily agreeing to have someone repave your driveway, deliver lawn fertilizer, or put a new roof on your house.
The consumer may cancel the contract within three business days. A contractor must provide the consumer with a copy of the contract, a cancellation form, and information about the right to cancel. A consumer that decides to cancel must do so in writing and it must be postmarked by midnight of the third business day.
