Now well into in my 80's I would like a Blue Badge for its convenience, but I don't want to have to have one, though I do have high blood pressure and am asthmatic and even though living in a town built on seven hills, some very steep. I do get annoyed at the amount of bludgers I know who are just as fit as me, go dancing, play bowls etc and still have 'the badge' some get a new mobility car every couple of years so they can go dancing (or so it seems), some have hidden disabilities, some very well hidden. In our town a one legged man was denied a badge, but a clinically obese woman (self inflicted!) was granted one.
However I always think, be careful what you wish for, a friend took advantage of his wife's badge on every occasion possible (how she , a dancer, got one I don't know) alas he had a stroke and cannot now walk and all his money cannot buy him a cure. The rules for applicants should be tightened not expanded to cover self indulgent eaters and their ilk, nor does stuttering or being dyslexic prevent you from walking, alas it does qualify you to become a para-olympian
