who made up that figure 144??

... someone's can dictate they will die at age 13...
nothing can change that regardless of which path is taken.. because all ajoining path's will lead back to the same fate .. death at 13...

thats why we know our ultimate fate.... but we dont know the time of our ultimate fate...
because that time is an unknown quantity to us...
therefore u cant say.... i was meant to die at 26 but i did this or that... and that altered my time of fate....
no...
because i said that time is unknown...
so..
we all die when fated to die... because we dont know the alternativ.. routes...(if there are any)
