Passion: expiration date

When people say, "we've been together for 10, 20, 30 years, and the passion is like the first time" - it's a lie and self-deception. The lifespan of any passion in a permanent classic relationship is 3-4 years. After this period, it may randomly increase and subside for a few more years, but eventually comes to naught. And this is normal. Therefore, classic relationships based only on passion last a couple of years at most, and then they fall apart if there is no other common ground between people. Another point: after being together for 3-4 years, people break up and then suddenly get together again, the passion between them may reach its peak again.
