Gentle (Age 13 - 15 years)In this wash the child is washed gently, he has no tensions, no stress. Children of this age are like kaccha nimbu, they don't know anything, but they are eager to learn. The school is enjoyable, some have few girlfriends, and life seems on the right track for them. They are gently advancing to face hardships further.
Heavy (Age 16 - 18 years)There is a lot of tension. A child has to manage between 12th standard studies, tuition, entrance exam coaching, etc. They get a sound bashing from their parents for not getting enough marks. This age marks numerous breakups between relationships. Some people get pimple and get depressed about their looks. This period of life is really heavy on mind. Unfortunately some guys cannot bear the heaviness and commit suicides.
Normal (Age 19 yrs - until we get a job)After the heaviness, the teenagers are quite matured and ready to face life. Some learn it the hard way, some take it easy. Studies are less as compared to the heavy phase, and students easily pass either by cheating or studying. Regarding relationships, your dad is always angry with you, he always complains about you getting less marks. Love relationships get good as all are matured enough. This gets normal until you get a good job.
Then comes the spinning mode (like a spin dryer). You keep on spinning and squeezed until all water in your body is pulled out. At last you stop when you're dried and laid to rest and your soul departs. This is how life ends.
