Do you really need friends?
In short, the answer is yes. A strong network of friends reduces the risk of making bad decisions and lengthens life. The video goes into more detail about online vs real life friends, and how many friends is too many friends. Essentially, though, friends are important to life so if you find yourself in a place where your circle is getting smaller and smaller, don't be afraid to branch out and ask someone to a movie or to lunch. You never know who might be looking for a new friend, too!
