Well I don't know how old you are, but trust me at 67/68 years old keeping your own house and garden respectable is a bigger enough task for most, without going out to do it for someone else, and even if one were so lucky to get such a job the pay is peanuts, either for early mornings, or late evenings, at max 2 hours per day, that's not going to pay household bills/ rent. They just want you to die before you get chance to draw any amount of pension.
