Having a lot of friends increases happiness in life.

I agree that having lots of friends do increase life happiness but depends on what kind of friends you have. Some friends do give good influences and some are not. But, if you can categorize your friends then this will be the lead to a more better life. Friends symbolizes your presence and helps you gain more confidence for yourself. Your thoughts and views change. Your fears and depressions are being freed.Because, you are able to be yourself exactly the way you wanted you life to be. They help you in many ways and can extend unconditional understanding of your shortcomings if you have well treasure friends. However, though you have many friends to be happy, there will always be some of them who will you realize to be a friend for life and that is the best reward you can being his friend and your friend.

I agree with you. Having a lot of friends could lengthen our life span because being with good friends could make our lives happier. It's like communicating through them, spending time with them, sharing all the good memories and the laughter with them. It's also one way of talking to them how you feel, channeling to them your emotions, and healing your soul. Being with good friends could make us feel important and loved, and that's what should matter most.
