Of course, if we are comparing, for example, tobacco, if we are waiting tens of years to get final proof, during those tens of years people are exposing themselves to tobacco or another agent that is considered as safe because we don't yet have final proof. It means that they will get health problems during these 50 years or over a long period of time when we are waiting for final proof, final evidence.
There is this difference. When we have an agent that might cause health problems and we're waiting for final proof, and we have to consider tens of years of waiting, we should think this way. What is better, to implement precautionary measures right now and wait peacefully for those tens of years for the final evidence, or should we continue business as usual, and in case it appears that this health problem materializes, then during these tens of years of waiting people will get this health problem, meaning a large part of the population?
In the case of cellphone radiation, of course, we are talking in the sense that we always have to consider seven billion users.
