1. It is estimated that about 40 per cent of the world's population use social media, and many of these billions of social media users look up to influencers to help them decide what to buy and what trends to follow. An influencer is a person who can influence the decisions of his or her followers because of his or her knowledge or special knowledge in a particular area, e.g. fashion, travel, or technology. Influencers are now seen by many companies as a direct way to customers' hearts. Brands are now asking powerful influencers to market their products. With some influencers charging up to $25,000 for one social media post, it is no surprise that more and more people are keen to become influencers, too. If you are one of them, then here are five tips on how to do it.

2. Choose your niche: What is the area that you know most about? What do you feel most excited talking about? Find the specific area that you are most interested in and develop it.

3. Choose your medium and write an interesting bio: Most influencers these days are bloggers and micro-bloggers. Decide which medium – such as your own online blog, Instagram or Snapchat – is the best way to connect with your followers and chat about your niche area. When you have done that, write an attention-grabbing bio that describes you and your speciality area in an interesting and unique way. Make sure that people who read your bio will want to follow you.

4. Post regularly and consistently: Many influencers post daily on their social media accounts. The more you post, the more likely people will follow you. Also, make sure that your posts are consistent and possibly follow a theme.

5. Tell an interesting story: Whether it is a photo or a comment that you are posting, use it to tell a story that will catch the attention of your followers and help them connectwith you.

6. Make sure people can easily find your content: Publicize your posts on a variety of social media by hashtags and catchy titles to make sure that they can be easily found. There is no point writing the most exciting blogposts or posting the most attractive photographs if no one is going to see them.

7. Most importantly, if you want to become a social media influencer, you need to have patience. Keep posting and your following will gradually increase. Good luck!

The average life expectancy in Vietnam is approximately 71 years for men and 76.4 years for women. This gender disparity is often attributed to differences in lifestyle and health-related behaviors. Women generally exhibit healthier habits, such as consuming less alcohol, smoking less frequently, maintaining a balanced diet, and paying greater attention to their physical well-being.  However, life expectancy is shaped by a variety of additional factors  . For instance, individuals residing in economically disadvantaged regions often face limited access to healthcare services, nutritious food, and opportunities for rest or physical activity , which can significantly reduce their lifespan. Educational attainment also plays a crucial role. Research indicates that individuals with higher education levels tend to live, on average, three years longer than those without a university degree. This is likely due to improved socio-economic conditions associated with higher education, such as better employment prospects and access to resources that promote health. Furthermore, benefiting from advances in medicine and medical technology people can lead a healthier and safer life, which results in enhanced life expectancy. Ultimately, lifestyle choices are critical determinants of longevity. It is crucial for individuals to adopt healthy habits, such as maintaining a nutritious diet that provides essential nutrients, and avoiding harmful behaviors like smoking, which brings about a wide range of both physical and mental changes in people’s health, leading to a longer expectancy.
