Nanny must have hated swimming as a child, for she certainly seems to have it in for swimmers these days.
Her chums at Huntingdonshire District Council have come up with an observation of the "bleedin obvious"; namely that people who swim may drown.
To this end, they have stated that those who swim in lakes and rivers face a "very real" threat of drowning.
As if that were not enough, they also warn that people who swim there may catch Weil's disease.
Pat Knight, countryside services manager, said:
"It is important people of all ages are informed of the risks and take responsibility for their own actions.
Swimming is not permitted in the untreated waters and must only occur in supervised swimming pools.
When an injury or incident occurs it causes distress to many people."
Nanny has placed her Council Rangers on full alert.
Anyone found swimming will be told to get out of the water.
As if Nanny has not said enough about the dangers of swimming, she also warns that you might get cramp if the water is too cold.
Remember folks, "The risk of drowning is very high."
However, Nanny does say that we should travel and work as normal in London.
Her risk scale needs some adjustment I would say.
