It's Ironic

There are so many ironies of life. Here's one of them:

Isn't it ironic that the most useful things we learn or skills we acquire that we can apply in our life are learnt in primary school? And that as we get promoted to secondary school, the things we learn get more and more useless? At least, more useless than what we learn in primary school.

In Primary School...

#1 We learn how to read the time
How useful is that? How useless would you be if you don't know how to read the time? Very useless. You would be either running late or early all the time. How useless would you be if you don't know how the exponential graph looks like? Not very useless. No loss at all, I would say.

#2 We learn how to count
If your name were Adam, how else would you know the Benny cheated you of 4 apples that you got from Charlie instead? You won't be charged more by the uncle selling chicken rice, too. That's a plus.

#3 We learn profit, gain and percentage
How useful! In primary school we can buy 10 packets of the 10cent/packet seaweed and sell it to that kid who never steps out of class at a profit of 5cents and then proceed to the bookshop to buy a new colour of shaker mechanical pencil when we've earned enough. Then in secondary school, it's an advantage to calculate how much marks we can afford to lose if we just want to pass, and how much is 75% so we can barely get that A1.

See my point now? Okay, maybe I'm manupilating everything so I can prove my point, but seriously, don't you feel that the higher you go in education, the less practical it gets?
