I would be very well-intentioned but disastrous in that job. The mind is affected with age by age because of age. Just as the physical body becomes limited as it never was before the mind becomes limited as it never was before. It doesn't get better with time. It gets worse. Add to the being ANGRY 24/7 as Bernie Sanders always seems to me to be and what are you going to have? Well we could elect him and find out. Or we could pass and look for someone not as angry who is at the TOP of his/her game and NOT sliding/slowing down. Your choice. Different strokes. I am old and I don't want old to run my country. Why do YOU?
