Everyone has a personal view about single life. I also have one.
In my eyes, Single-life is perfect and peaceful till a certain period of life. After that, Staying alone will become a curse for most of you. Especially, The best thing in life can be building a new peaceful family.
Single life is like a calm, deep, and crystal water river that never dries up. There are only a few ripples to cure boredom. But, Mingle life is like a rough water river. There is Adventure but no guarantee.
After a certain period of time, it will be hard for you to stay alone. You need some elements to enjoy your life. Your wife, children, old parents.
