At 20 years "foreign country" and "hometown" are the same. (No matter where you are, you can always adapt)

● At 30 years, "night time" and "daytime" are the same. (A few days of no sleep, does not matter)

● At 40 years, "highly educated" and  "less educated" are the same. (Less educated people may even earn more money)

● At 50 years, "beauty" and "ugly" are the same. (No matter how pretty you are, at this age, wrinkles, dark spots, etc. can no more be hidden.)

● At 60 years, "high position" and "low position" are the same. (After retirement, even a peon will avoid looking at his boss)

● At 70 years, "big house" and "small house" are the same. (Joints degeneration, hard to move, only require a little space to sit  .)

● At 80 years, "have money" and "no money" are the same. (Even when you want to spend money, you don't know where to spend)

● At 90 years, "Sleeping" and "waking up" are the same. (After you wake up, you still don't know what to do)

Take life easy, there are no mysteries to be solved. 

In the long run, we'll all be the same.
