You want to build a small hut in your garden, what dimension should be the carpentry ? How much concrete do you need ? How many tiles ? You are in top of your leader and need to put the roof at 17°, how do you do without protractor ?

You have to put chemical in your pool, how to compute It's volume ?

You have to write a letter by hand for whatever administrative reason, how do you do ? Some administration do require hand written statement.

You're in a hotel where floors are numbered in roman, how do you go to your room ?

You read a book, how do you know in which chapter your stoped ?

You are in a real estate agency to buy a land. The land is trapezoidal and you notice the surface doesn't correspond to what is written because those retard don't know how to compute area of trapezoid (true story).

And for god sake, life is not about just doing things that are useful ! Just watching the stars with your kid, and tell him "that is Mars and that is Jupiter", doing quiz with friends and win a free beer, growing its own sodium Cristal in a glass, writing poesie, all of those are completely useless but are the best parts of life !!!
