For many people, there is only one source of energy for one of our oldest stimulants: caffeine. Caffeine can decrease fatigue and increase alertness, but is it really beneficial for us?

Scientist Charles Czeisler says that we consume caffeine to stay awake but later to prevent us from getting the rest we need. Caffeine consumption has also been linked to an increased risk of some cancers and bone diseases. Additionally, heavy caffeine users’ moods fluctuate from high to low, and they suffer severe headaches.

However, studies have shown that caffeine can help ease muscle pain. Moreover, it improves performance on tasks like solving simple math problems.

Caffeine has real effects, but they are usually moderate. This is why caffeine is found in so many of the world’s most popular beverages.

She does not teach us to throw out things ruthlessly. On the contrary, she treats her belongings like living things. She bought a new cell phone when she was in high school. Then she sent a message to her old one: “You have been helping me for many years. Thank you.” After receiving the text message, she said, “Great.

This illustrates her point: we must respect our belongings even when throwing them away.

We choose our belongings. So it is difficult to get rid of them. She says that asking if we have difficulty throwing away a certain item will help us discover our life values.

We learn to set priorities when we organize our rooms. And when we throw away old things, we learn to make decisions. Tidying up can transform our lives. So if you are unsure of your future, start by sorting things out.
