My whistle up the Shard has been duly noted. Ken Austin rang with news of the website www.willpearson.co.uk/virtual.tour/shard-360-dusk that gives you a 360-degree view from the top.

I immediately thought of Dorinda who sent me a supportive email to say she is a fellow vertigo sufferer and had a very bad moment at the top of the Liver Building in Liverpool when she worked there in the Swinging ‘60s. It was the 14th floor and “the tower was swaying in the wind and my legs turned to jelly. I sat down and I can tell you, I went all the way back down the spiral staircase, into the lift and back to the ground floor on my bottom. I have never forgotten it”.

Like me, Dorinda has also been terrified along the Amalfi coast, in Italy, and for another addition to the world’s top vertiginous journeys suggests going, by coach, up to see the volcano on Tenerife.

For those unable to ascend the mighty Shard, I would recommend the website... as long as you have sound mouse skills.

If you whizz round too rapidly, it makes you awfully dizzy.
