Untreated heart attacks may slow blood flow enough that blood may start to clot and prevent the flow of blood to the brain or other major organs. Extremely low blood pressure can also result from drug overdose and reactions to drugs. Therefore, brain ischemia can result from events other than heart attacks.
What Is Return Receipt? The USPSÂ® offers a service called Return Receipt that gives you peace of mind by providing evidence of delivery in the form of a postcard signed by the recipient or an e-mail with an electronic copy of the recipientâs signature. Return Receipt is available for Priority Mail ExpressÂ®, Priority MailÂ®, First Class MailÂ®, Retail GroundÂ® and Media Mail.
This reminder informs the person a USPS Certified MailÂ® letter is being held at the local Post Office for pick-up. They must go to the Post Office to Sign for the letter and pick it up. If no one picks up the letter after 5 to 7 days, USPS will leave a second delivery notice. Again the delivery slip reminder is left by the letter carrier. Finally after 5 to 7 days the final delivery attempt is made to the delivery address.
