Hmm an 81 yo with a spatula with grab as extender - probably good for at least 2 yards every day if you apply hot food and drink regularly.

However I can smugly report I have cleaned paths up for two elderly neighbours already and am equipped with shovel and big brush - not quite full snow plough category but good enough to find a zimmerframe.

If you do need help PM me - I will be in Forest Hill and environs for the rest of the day (Monday).
