The importance of Russian tourism:

Egerša from Baikal said: “He comes here alone!” Someone is a foreigner! On the shore of the Baikal walked, walked, came and showed gestures - drink, say, I want! He had little to drink!

xxx: People who are accustomed to comfort can just fantastically hinder."

There are no parasites in fresh water.
The fresh water is crystal clear. You can drink it raw and not be surprised by the frequency of approaches to the toilet afterwards!
Okay, let’s say he decided to drink from the Baikal.
1) How to get water? Do you always have a cup or bottle with you?
2) water on the shore and in the upper layer of water, even on the Baikal is not the cleanest, must be taken away and picked up where deeper. To go into the water? Taking a boat to sail? What if the winter - to climb into the crossing or just lay out of it?
3) raw water from a freshwater reservoir (not from an artesian well or from deep layers) should be boiled. Does a tourist have to fire? As long as he has something to boil that water.
And if he didn't stay in the tent with a night, but just came for a day's walk, what about him?

Egersha may have been used to living in the circumstances of the campaign all her life, and she has seen nothing except Baikal, but it is necessary to remember that not all of them are such narrow specialists!

And these people complain that no one goes to them! Yes, damn, maybe you would go, but you and drink without a quest won't get out, and the whole internet will be celebrated!
