PIP reviews over 65 years

Hello, I am over 65 years old and on PIP both for the daily living allowance and mobility. My last review extended the benefit for ten years. Is this the maximum extension time given or are some people awarded ongoing?

I have mislaid the letter giving the exact date but I am fairly sure the review was due this year. My health has deteriorated but not to the extent I'd be given an increased award. I have been on PIP for nearly twenty years. I had heard that the DWP were doing a light touch review for some people, but am unsure who that applies to? Having been on DLA and then transferred to PIP and having to go to Tribunal the thought of having to do a full reassessment is duanting! I am 74 yrs old.

Thanks.

Thank you both for discussing this as I too have questions regarding this but although my age is the same, im not due to move from UC to state pension yet - plus apparently my light touch 10 year review is due in February and I'm sick with worry at the prospect of despite my complex medical picture/conditions resulting in enhanced on both counts either remaining the same or have got worse, being forced into a new full review and being taken off PIP and losing enhanced mobility in particular because theyve changed me to Attendance allowance instead ... Im so ill worrying about this. Im 65, birthday in July '61 ... not entirely sure where/when my crossover to state pension will be, so not sure whether Im making myself sick unnecessarily because any review would happen before I would be forced onto AA ...?
Am making this a seperate question so as not to impinge on the original
