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.
Do not include Sundays or national holidays when counting the three days from the date of your signature. To cancel the contract, sign and date both copies of the Notice of Cancellation and either mail or hand-deliver one copy to the merchant by midnight of the third business day after signing the contract.
