I feel like two people most of the time. On the face of it, I have the physical attributes of a sickly 90 year old. But mentally, I have stayed about the same 'age', or mindset, as when I first got married and had a kid. That was my demarcation line between just messing around aimlessly, and getting down to business. And ever since then, 30+ years ago, I'm the same guy inside. Not old, not young, just 'me'. I suspect I always will be that guy. And I suspect that truly old people also feel this way. I'm noticing it at my relatively young age because the disease makes the two "Me's", physical and mental, feel so totally different. While I don't like the health issues, of course, I'm grateful whenever I see that I'm still the same guy underneath. Don't want to lose that.
