Tjanet:
As I aged I found my body didn't absorb electrolytes the same as it did when I was younger, so I was getting muscle spasms (Charlie Horses) in my calves and shoulders, and after moving to the city and city water, I do not like the water. I had to start drinking Gatorade or Electrolyte water, which is bottled with electrolytes in it. That keeps my level of magnesium, potassium and salts high enough to stave off dehydration from sweating while working in the yard or walking 3-4 miles a day.
