The 'Ideal' Age

When is the ideal age:
to be idle?
to fall in love?
to stop drinking your mother's milk?
to stop wearing diapers?
to retire?
to move out on your own?
to declare yourself an adult?
to stop running to your family for help?
to save money in the bank?
to get a fracture?
to start threading your eyebrows?
to stop eating 'cerelac'?
to start using abusive words and get away with it?
to be stressed about work and life?
to give up on everything you hold dear for money?
to say you are old?
to make out on the back seat of your car?
to cry watching mushy movies?
to roll around in the mud?
to swear off junk food?
to clean out your closet?
to think about the ideal age?
