It makes a big difference to me if I am familiar with the terrain. Then I have no problem. In Winter here in the UK, when I get up, usually 6-00am, it is very dark. However, I am always amazed how I can find my way with no lights, and when I have closed the bathroom door to avoid waking my wife, I can put my hand unerringly every time on to the small hanging switch. It is like a blind person with an enhanced sense. In unfamiliar terrain, I generally need to hold on to something. My balance is much worse.
Happy Xmas to all, from Merry England.
I am hoping to meet Greg this week, who is in England for Xmas.
