1. Email to Lan:
Hey Lan, Hope you're well. I had the worst hotel experience on my holiday. From the moment I checked in, things went south. The room was dirty with stained sheets, the bathroom had broken tiles, and the Wi-Fi was almost nonexistent. To top it all, the staff was so unhelpful. I can't believe I chose this place. Never going back there! Hope your vacation was better. Take care, [Your Name]

2. What is the Best Invention of the 20th Century?
The Internet is, in my opinion, the best invention of the 20th century. It serves as a platform for information, communication, and entertainment. It has revolutionized the way we live, making it possible to connect with anyone, anywhere in seconds. I use it daily for work, research, and staying in touch with friends. Its accessibility and utility make it a groundbreaking tool, bringing the world closer and making information more democratic.

3. Increasing Your Health:
To boost one's health, start with a balanced diet rich in whole foods. Consuming vegetables, fruits, and lean proteins provides essential nutrients. Exercising regularly not only strengthens the body but also elevates the mood. It's equally vital to allocate time for fun and leisure, ensuring mental well-being. Lastly, unplugging from technology allows the mind to rest, helping in better sleep and reducing stress. These combined actions lead to a healthier, more fulfilling life.
