I'm only 50 and gave up driving some 8 years ago now due to being so badly depressed that I felt I would be a hindrance on the roads.
My health deteriorated quite badly at this time, plus we had an road accident whilst on a bus, leaving me with another life long heart condition to go with the two I already had.
It has impacted on my life to the point of thinking twice if I really need to go somewhere as I usually use taxis to take me direct and back again. Or I travel with my brother in his car. This is because I only have a certain amount of energy and so if I traveled on the bus, then my time where I was going would be very limited and I would have to go home again very soon. I now cannot travel to my DD even if I wanted to because it takes it out of me too much to travel there, stay for a couple of hours to see the children and then travel back. My legs swell and I am laid up then for days afterwards due to my heart conditions. So now I choose not to go.
I do go on holiday because I can go one way, rest for a few days and then travel back home. If going out at home, I am away from home only a couple of hours and then back and back into bed for a rest. I am waiting for a heart valve operation so it might make me feel better again when I have had this and recovered, who knows.
But I am here, and there are plenty worse, so I get on with it.
