The answer, in my case, is yes to all of the above. The horses, the cars, the fire, even the soap! Could I survive?? Probably not! I’m diabetic and I have had major spinal surgeries. I’d have made it to age 50 or so and probably would have done well until then. My first major surgery was at age 53 and I might have made it another five or ten years in serious pain, but after that paralysis and loss of some bodily functions would probably have done me in. The diabetes developed at age 57 and likely would have finished me off in due time.
The medical developments are what would be missed in the wayback journey for a lot of us “boomers”. For those arriving in later generations, it would be MUCH WORSE for most of them!
