Learning 2=4 is a very important piece of knowledge that changes our lives.
Learning how to drive is yet another event that changes our lives, and learning how to read is one of the biggest things we can do to change our lives for the better in this world.
What if I kept information to myself which could change your life forever? This would be very selfish of me.
In fact, it could be considered hateful.
To withhold information I have found which could benefit you now and forever would not be doi.
