I've been drinking Shangpin Bama. I've been drinking for over two years. I used to feel weak and sleepy. Slowly, I feel much better now, full of energy, and feel energetic every day. It tastes good and soft. As for the effect, long-term drinking will definitely have an effect. Your friend also told you that there are many long-lived old people in Bama, and people there generally live a long life. The main reason is because of this water. If you have the conditions, I also recommend you to drink. Only when you are healthy can you have everything.
