标题：Expiry Date - A Reminder to Act Quickly

Every item has an expiry date, whether it"s a medicine, a voucher, or a contract. When the expiry date arrives, it means that the item is no longer as effective or valid as it used to be. This is why it"s important to act quickly when dealing with items that have an expiry date, so that they are used up before they become unusable. For example, if you have a medicine that is about to expire, you should take it to the pharmacy as soon as possible to be replaced with a new one. Similarly, if you have a voucher that is about to expire, you should use it as soon as you can to avoid losing any money. Finally, if you have a contract that is about to expire, you should negotiate a renewal as soon as possible to avoid any potential issues down the road. Expiry dates are a reminder to act quickly and avoid any unnecessary waste or loss.
