These things can't be left for a long time, and when you increase your knowledge, collect them and take a look

"You know what? There are some things that really can't be left for long. My friend Xiao Wang said to me while rummaging through the refrigerator in the kitchen. I put down the book in my hand and walked over curiously.

"For example?" I watched as he pulled out a box of blueberries from the fridge that he bought last week.

"Look, these blueberries are starting to mold." Xiao Wang said helplessly. He tossed the moldy blueberries in the trash and continued to check on other things.

Inner Monologues: It dawned on me that in our daily lives, we often buy a lot of things and forget that they are not always 'evergreen'. It's not just food, there's a lot more. I think it's a good opportunity to find out what can't be left out for a long time so that it doesn't go to waste.

"Actually, it's not just food, but also medicine and cosmetics." Xiao Wang continued, taking out some medicines and cosmetics from the drawer and checking their expiration dates.

Conversation: "Wow, this bottle of sunscreen has expired for a year!" I said in surprise, looking at the bottle in my hand.

"Yes, expired sunscreen may not mold, but it is less effective and may even be harmful to the skin." Xiao Wang explained.

I nodded, a hint of surprise and gratitude in my heart. I didn't care much about the shelf life of these everyday products, but now it seems that this is a habit that needs to be changed.

We went on to discuss the shelf life and storage methods of some common items, such as:

• Coffee beans: It is best to use them within a month after opening to avoid spoilage.
• Spices: Although they are not easy to spoil, they lose their aroma and effect after one year.
• Battery: Storing it for too long can cause leakage and damage to electrical appliances.

This collation made me deeply realize that reasonable purchase and timely use are important parts of avoiding waste.

End of article: After tidying up, Xiao Wang and I sat in the living room, drinking freshly brewed coffee. I secretly vowed in my heart that I would pay more attention to the shelf life of items in the future and be a savvy consumer.

This experience was small, but it had a big impact on my daily life. By knowing what things can't be left out for long, I not only save money, but also avoid possible health risks. This kind of knowledge is indeed worth collecting, learning slowly, and practicing slowly.
