A choice where the answer is loaded too far to one inevitable reply.
After all , why do 6 million + care under the terms and conditions as laid out in the first posting ?
The real answer is because there is NO choice !

Age ? Not a problem. As young as 5 , as old as 103 , we take them all !
And , when your caring days are ended , don't expect us to provide a " Former Carers Welfare Officer " to help you adjust to life on the outside. We only provide that service to prisoners !
If you sign on at your local job centre for JSA , we will not take into account Carers Allowance as contributions , we will only pay you JSA if your income is below the financial limit currently in operation. Sorry , but caring is disallowed for automatic JSA. So , if he cannot afford to lose £ 62.50 per week when your caring end , get a job like everyone else.
" Caring days ended and residing in social housing , and not on the tenancy ? Oh dear ... bad luck ... your local cardboard city awaits while you find yourself a job and somewhere to live. "
