Lindy,
I think you captured the critical thing for me. "The immortal feel that you have....the feeling of everything being possible." I've had many jobs in different professions throughout the years. And very long-lived parents (both into their 90s). So when I hit 50 I still felt I had many more years to find my place in work and the world. When diagnosed in 2001, that open window of possibly 40 years to figure things out, started to close and if closed fully seemed cloudy. Now the prospect of living into my 90s seems more a threat than an opportunity. But if I stay in today, I'm ok. I realized this weekend that just before diagnosis, I could no longer touch type and had hand-written a major speech. This week, given medication and exercise, I can touch type and did deliver a 20 minute talk without many obvious symptoms. So, who knows what my future will be, today is more than ok and I would not have envisioned this possibility.
