Btw, I have been in touch with Virgin Galactic about their suborbital space flight. I might actually do it. My age (65 in June) is an issue but not an insurmountable one if I can pass a comprehensive physical. Older people have flown in orbit, a far more demanding regime than a brief suborbital flight, and Dr. Storey Musgrave did arduous spacewalks at 61.

The cost is daunting, but it is a once in several lifetimes opportunity.
