Life will get difficult as we get older.
Especially in the old age.
There will be pain. Physical pain, mental, and emotional pain. And when you look outside the window, you'll see death, waiting to knock at your door.
There will be loneliness.
When you're young, there are possibilities. The circle will start getting completed. The boomerang that you threw will start coming towards you.
Guilt, regrets, all will start getting stronger. Because now, time is up. You had your chance.
Maybe, you'll want to meet that girl you loved for years. But never loved you back. How nice it would be, if she could at least spend the last few days with you. She never cared earlier. Will she even remember you?
You won't be able to walk properly, and your children will hate helping you. They might not even help you at all. And you'll just want to die because you can't bear that guilt anymore. But you can't, because you didn't live life thoroughly. You missed out. Missed out on one thing or the other.
Your body won't support you anymore. It wants to merge into earth, where it came from. Your time is up.
