I understand where you are coming from but in my case, (yes, I am over 70!), the ambulance would be constantly being called!

Working with horses, climbing over/through fences, out in all weather, I'm constantly falling over!  Just recently I was knocked out cold when, rather foolishly, I bent down to pick up an empty feed bucket and Posh, (one of our horses), rapidly lowered her head onto mine to see what I was doing.

If you spoke to anyone who knows me they'd tell you I'm unbelievably clumsy - tripped over a curb in the Tesco car park yesterday because I wasn't looking where I was going 

About 20 years ago my arm started to go numb and it wasn't until I had an MRI that the cause was discovered - I'd broken a vertebrae in my neck that healed itself but the bone growth around the break was compressing the spinal cord.  Not sure how I originally broke it but maybe that was an occasion when an ambulance should have benn called.
