After all, either you live very high standard of life or low standard of life . . . there is no question of low standard of life. The proper upkeep of health is cleanliness. If you keep yourself clean, then your, I mean to say, problem of health is solved. Simply cleanliness. "Cleanliness is next to godliness." That is also an English proverb. And in Sanskrit literature also, bāhyābhyantara-śuciḥ (Garuḍa Purāṇa): "One should be cleansed within and without."
So without, you can clean yourself simply by water. By the laws of nature you have got enough water so you can cleanse yourself outside by water. There is no necessity of soap. There is no necessity of anything. Simply if you wash your body with water sufficiently. Of course, in your country it is cold country. In India, common people, they go to the river and take bath very nicely, because it is a tropical climate; there is no trouble. So you can cleanse your body.
