Because change is basically the only constant in science- Energy, matter… It’s always changing. Morphing, merging, growing, dying, it’s the way people try not to change that is unnatural. The way we cling to the way things were instead of letting them be what they are. The way we cling to old memories instead of forming new ones. The way we insist on believing despite every scientific indication that anything in this life time is permanent. Change is constant. How we experience change, that’s up to us. It can feel like death or it can feel like a second chance at life. If we open our fingers, loosen our grips, go with it, it can feel like pure adrenalin. Like at any moment we can have another chance at life. Like at any moment we can be born all over again.
