标题：Life Cycle of a Product and Its Expiry Date

In today"s fast-paced world, we encounter various types of products that come with their own expiry dates. From food items to medicines, everything has a limited lifespan that needs to be respected and adhered to. For instance, a food product that is past its expiry date may no longer be safe to consume, while a medicine that has expired may no longer have the desired effect or even cause harm to the body.

Understanding the expiry date of a product is crucial because it indicates how long the item can be stored and still be considered safe and effective. It is essential to discard products that have expired or are nearing their expiry date to avoid any potential health risks or wasted resources.

On a personal note, I always make it a point to check the expiry date of the various products I purchase, especially those that are crucial for my health and well-being. Knowing the lifespan of a product allows me to plan my purchases accordingly and ensure that I am not left with expired goods that could have been avoided.
