It follows, from the need to avoid imposing a sentence on you that is crushing, that I must take account of your age.
However, it is clear from the authorities that advanced age can never be a justification for a sentence which is not otherwise fairly proportionate to the relevant offences or otherwise inappropriate. It is also clear from the authorities that there will be some cases where the circumstances are such that the offender has forfeited his or her right to an expectation of useful life after release from custody. Given the mitigatory factors that I have identified in your case, I don't think that point has yet been reached, so I do take into account your age in determining the sentence in order to avoid imposing a crushing sentence.
In my view, a total sentence of 8 years and 6 months' imprisonment appropriately reflects your overall criminality in committing the offences, having regard to all of the circumstances, including, of course, your guilty pleas and the need to avoid imposing a crushing sentence.
This sentence, in my view, appropriately reflects the balance which needs to be struck between imposing a total sentence that is proportionate to your overall criminality and the need to avoid imposing a sentence which destroys any reasonable expectation of useful life after release from custody. Were it not for your age, I would have imposed a significantly longer total sentence: AB 69 - 70.
