As someone who currently spends �35.00 a month on swimming, free entrance would appear to be of benefit to me.
However I can see why others are concerned about the money needing to be raised to fund this. On the radio programme I heard it was to encourage people to take exercise so that there will be a saving in the health costs.
What the difficulty is always with a preventative health scheme is that there isn't a easy way of measuring what exactly the take up and benefits to health will be. But, surely an incentive to increase public health and reduce health costs must be a good thing and might be economic sense
