A friend is designing a new house and making sure it’s wheelchair accessible for her old age. That’s not the future I envisage.

For a start, I’m having Alexander Technique lessons to keep me mobile. One of my teachers is 90 and she’s a fantastic role model. She has so much strength and energy, she helps me off the massage bed at the end of the lesson and I land in an upright position with no effort from me. You wouldn’t think she’s twice my age.

Also, I hope that before long we’ll be saying wheel chairs are, “So last century.” There’ll be small motorized vehicles, like Segways, to help us get around, and if that’s not enough, we’ll attach robotic devices to our clothes to help our muscles. Exoskeletons are already being tested in Japan. See below:
