What is true love and what is the right age for it? (Does it even exist?)

True love is when someone see your every flaw and still accept you for who you are. Someone who won't come at you to change who you are as a person but to accept the challenge to cherish your true self the way it is. Imagine your whole body smashed with mud, when someone still hugs you while all the mud is all over you. That's true love!! True love is regardless of numbers such as height, weight and age and factors such as race, background or social/financial status.

Of course true love exist. Everyone has their "the one". Although, some people would be disagree with me. Those who attend to believe true love is fake are victim of their wrong choices, actions and lack of understanding of true love from the first place. They pick up the wrong road. They get hurt. They never realize their own mistakes but give out the result as true love is as fake as it can get.

The more you seek the less you find. Human is nothing without a purpose. And you can't share your life with someone else when you have no life nor a goal, when you haven't started your life's journey. If everyone live their life, realize who they are and where they want to be and who they want to become, following their path, then they'll see before they know, their right person will arrive just out of nowhere and they'll share each other's journey together.

Love doesn't know age. But i believe a stable love occurs after teenage period.

I think it can differentiate between people in small increments.

I think when we first find that "crush" we are infatuated with that person and can even obsess about the "Idea" of being "In Love". People who are in love seem happy, content and safe. Who wouldn't want that?

Being truly "In Love" means you give that person all of you (which is tough to do for most) . . . When you are young "Giving all of You" is difficult, because you have discovered exactly what it is that "YOU" consists of.  I think for some this can be achieved earlier (probably between 19-21), for others it can take them into their mid to late 20's.

Always love a person for who they ARE, not who you can make them BECOME.

You need a basic framework about love to learn what it is and how the different types thereof can be better understood.

Here's the classic book on the subject.  It's still available and the concepts covered therein have proved quite useful to me since I first read it when it was originally published.
