About the popularity of researching family history and its positive effect Exploring one's family history has become increasingly popular in several countries all over the world. In my opinion, knowing the past of one's own family help create one's own identity, which I believe is beneficial for individuals eager to know themselves and our society in some ways. There can be several reasons why people are curious about the history of their own family. However, I argue that one of the most important reasons is that people are born with desire to know. Despite the cultural differences, people from different countries share the interest in knowing their origins and themselves better. Researching one's family history is more than constructing genealogies. In fact, people are rewarded with knowledge of where they come from, knowledge that shapes their personal identity and creates a sense of belonging. Exploring one's family is not only a journey to discover one's origin. It also helps to clarify and remember the relationships that have long been forgotten. By doing so, people might feel more connective to the relatives who live a great distance away. Also, a deeper understanding of the family's past facilitates intimacy with the elder in the family. Thus, to know more about family history helps bridge the distance between separate and unfamiliar relatives and gap between generations, making more interpersonal relationships possible.

Negative effects of Social Media It is considered by many people that social media, for example Facebook, has influenced both individuals and society negatively. In my opinion, social networking sites are detrimental to individuals and our community in many ways. For many spending time on social media has become a daily routine, through which they socialize and keep contact with friends who live a great distance away. However, some of the users are so addicted to social media that they put their work aside. The productivity of whole society might drop if most of its members waste half of their day on Twitter or are distracted continuously by FB's notifications. Another harm that social media causes might be more serious than it does to our society's productive power. Social media, as its name shows, is intended to better human's social life. However, many users of it sacrifice their "real" social activities for social life in virtual world. For instance, many people are so obsessed with their image on social media, while losing touch with people close to them in reality. They would rather put time interacting with followers on the net than attending family events or party held by their friends. Ironically, instead of strengthening interpersonal connection, social media becomes an impediment to it

In general, it takes 34-36 days to complete a whole cycle, and we can see there are 5 stages of the life history of the honeybee, from egg to mature insect.
