Geoffrey Wango, a psychologist says that friendship tends to decay past 25 years because this is the time that most of your social circles are limited to those you can meet with occasionally.

He adds that even though finding those that you can rely on as friends might be hard, there are those that stick by your side through thick and thin, those who don’t mind the fact that you have a family that you need to take care of, or work to do when they need you to go out.
