M. Curie Onsen

Smoking is legal, so why shouldn't taking a radon bath be? It's probably not a wise decision, but people have the right to give themselves cancer. However, it is a stupid thing to do because there are so many other onsens to choose from that have specialties of a more benign and pleasant nature. Why not go to Aso Farmland and bathe in wine, herbs, and flowers, go to Kurokawa and dunk your body in bitter cold mountain river water after soaking in minerals and heat and absorbing the abundant natural beauty, or get buried in sand after relaxing in a volcanic mud bath in Kagoshima? Going to the onsen allows one the sorely needed time to reflect and to analyze and learn from their stupidity (post hash wound examination and cleaning, nomihodai futsukayoi detox, etc). Developing cancer after routinely going to the radon onsen, one would seriously ask one's self "What the f*** was I thinking?" and then agonize over it. Now wouldn't that be ironic- a place of relaxation being the source of worry and stress.
