Hey Dan,
It's me, your 63 year old self. I've got some good news and some bad news for you. I know you want the good news first. So, you're going to meet Deborah, eventually. She is a wonderful person and you two will be as happy as any two people can be. The bad news is that she is going to be diagnosed with Parkinson's disease a year before you finally meet.
My advice to you is: start looking for her in 1991! That way you guys will have more that just 8 years together. You two are going to make an awesome team. Do not let her shrug off those first PD symptoms when they appear. Encourage her to seek medical advice as soon as possible, and stay active (she is going to love the PD boxing program).
RETIRE together as soon as you she gets that diagonsis. Tell her you love her every day, she is worth it. Stay by her side, and be patient as she slows.
P.S. Document everything, you'll need it for the book you're going to write.
