Like many others, I suspect, I will use an escalator or lift rather than stairs.
It's not that I don't exercise, I do, but I try not to get noticeably out of breath in public.
Anyway, I was working yesterday in Leicester (I travel all over for work) and the place I was visiting was on the 6th floor and......... you've guessed it, the lift was out of order.
I did it! OK, I had to have a little rest after each flight and when I got to the top I had to use my ventolin for the first time since I went on to Spiriva but I recovered my breath quite quickly really.
I'm quite proud.
