I have heard ponies say that living so long would be a curse. That it is a burden. That it can break a pony's mind. There is some truth to that. It can be hard to know that you'll always be left behind as others pass on. However, that is not the whole truth, I am also blessed. I have an opportunity to see history play out in front of me and tell future generations of the ponies behind the legends.
