I had a scheduled medical examination today. Amused by the doctor otolaryngologist. After examining my nose, he concluded that my nose is very dry and there needs to be moisturized. The further dialogue:

What would you advise me doctor?

There is very good sr-vo Aquamar, nose spray, contains seawater, ideal for daily use, convenient to use, etc. and only 300 p.

I - and a simple salt solution of 30 p. for a bottle will not be suitable?

It will be 10 times cheaper!

Pause, my questioning look toward the doctor

In the sense, there is no seawater there...Iii.. However, (apparently decided to fully rehabilitate) buy just salt, but better sea, and give yourself the solution, the proportions I will write.
