Yeah! There's always that. But then again you don't have to get phantom pain even if it's a possibility. Tinnitus has been compared to phantom pain. I think there is a thread about it on this forum where researchers have stated that tinnitus in fact is phantom pain in the auditory system due to the loss of input. Just like phantom limbs.
The thing is when I think about things like meaning of life I come to the conclusion that it's all about suffering. You just don't in which way when you're young. I couldn't imagine having this thing 15 years ago. Other people get something else, like cancer or ending up as paraplegics. But we all suffer in some way.
God I wish I could go back to those days. Being young and not knowing...
