Neither tbh. But if I have to choose, dying. Aging may be suck but you can always take care of yourself from early age and I also see aging as a beautiful thing especially if you're there with the ones you love. I'm not afraid of dying but leaving those people behind and not knowing anything about life thereafter seems worse.
lowkey aging. not just because I dont want to look old, but feeling old, not being able to take care of myself, losing my mind etc is terrifying. death doesn't scare me
