pip and esa

I went through my esa test over 4 years ago and scored 0 points on all counts, I did intend to appeal but after the follow up phone calls from the dwp decided not to, hind sight would have been a good thing. They said that because my wife was on pension credits I need do nothing as pension credits would pick up the short fall in our money when my incapacity benefit ceased, well you might ask what was I on incap for I am Diabetic and have been for over 20 years and have had very poor blood sugar control resulting in complications such as neuropathy etc,by the way conditions such as neuropathy come about from poor control and not through having hypo's, the tester for esa seemed to think hypo's were more important and after telling my specialist they said she did not have a clue about being diabetic. Funny thing after I got the documents from dwp it stated at the end that a review in the short term was advisable, guess what I am still waiting for that invitation but it does not matter now as I am retired and have been for 2 years. I also had an accident at work where I fell off an overhead crane resulting in an injury to my spine but to look at me people would think there was nothing wrong with me, what I am worried about is will the PIP assessors take into account my esa results, if they do then many points in that esa test were rubbish, one of which was, the nurse who took it said that i could carry out a conversation with her over a distance of 2 meters with no problems at all, what I said to her was that I watch peoples faces and can just about tell what they were saying but I could not lip read,I was at the time going through test for my hearing and now wear 2 hearing aids, just goes to show all the esa tests are for getting a 0 result and nothing else, also I told her that I medical documents with me but she said the copier had broke down so could not copy them, a fine thing.
Many years ago if you were claiming a benefit the date of the claim was taken when you filled out the claim form, PIP states that you cannot claim if you are over 65, well I have not yet made a claim for PIP yet but will have to, but I will be nearly 67 when I do, makes it a bit ridiculous as you cannot claim PIP if you are over 65 smacks of double standards.

I am currently getting dla and have been for the last 15 years, how would you know if the results from the esa test was used in reaching a decision about pip.
As in a previous post i know of 1 person that if they were invited to claim pip would lose their current dla because of their condition, ie no medication, no doctor or specialists reports, no history of doctors visits for the condition which would be alleviated with surgery, but because of their age, 2 years older than me will remain on higher rate of dla mobility, that is not fair to younger claimants who if had the same condition would not get pip

what do you mean must explain, is that asked for or stated in the report
