In most societies the general concept of freedom is that a person is free to do whatever he likes provided it does not prove detrimental to his fellowmen. But the concept of what can be detrimental to his fellowmen is becoming gradually more sharply defined than it was in the ast. There is a clear concept that a person does not have the right to take such risks that will likely make him (for the rest of his life) dependent on the support of the community. But his principles do not usually prevent him from climbing mountains, despite the known risks, and one can therefore hardly argue that it could prevent him from taking medicines on his own initiative despite the presence of certain (perhaps calculated) risks. It is difficult to define clear limits to the () of the individual in such matters, but a number of () might be proposed.
