I've been reading a few blogs which have sparked off some tangental thoughts which I thought might fit under the heading of coping.
Wedding shoes: I've never been able to wear heels, suits my particular style which tends to be forgiving tunics and trousers. My niece had a very posh wedding but it was in a marquee in a field so I decided to wear coloured baseball boots. V comfy and the red was a nice contrast with my blue outfit. And I'm a bit boho I suppose so noone thought it odd. I've also noticed a company in Sheffield which does sort of bespoke shoes and sandals and am about to try them out. I'll let you know how it goes but they arent frighteningly expensive (not when like me you own one or two pairs of shoes). I'll say more if they prove to be really good. But you have to draw your feet and send them off.
And I read about someone doing a trip to Paris and lugging bags in the metro. I find taxis and buses a complete godsend. No long flights of steps. Taxis can be expensive, but I try to economise in other areas.
Difficult basin/ sink taps: have you seen those tower taps with a lever? A very elegant way round that problem of turning on and off with aching wrists.
It'd be interesting to know other peoples strategies.
