Don't know but I'd buy a new one, I have two of them. The views expressed in my posts are not necessarily mine.
Standing near a window in Russia is more dangerous than walking towards the traffic on a motorway dressed completely in black. https://www.dailystar.co.uk/news/world-news/russian-energy-firm-boss-found-33932366
Years ago in Corfu I struggled because of breathing problems going ap a long, steep track going up to a restaurant. An old dear said watch how the locals do it. They did it by walking side to side like that as you are not putting as much exertion into it as if you were forcing yourself up a steep incline. That may well work, must do as so many were doing it, but next time, it was a very good restaurant with amazing views so we went again, I got a taxi.
Pfttt, I have no trouble getting to the bar, I give others the money and send them. The views expressed in my posts are not necessarily mine.
