To be fair, you’d have to use a per capita stat. El Salvador is too small of a country.

Exercise

No alcohol or tobacco

Eat natural and avoid sugar

No screen time 2 hours prior to sleep.

Reduce stress in life.

Sleep in sub 70 degrees and as dark as possible

Need to see how things go with 2-3 transitions of power within El Salvador. Unfortunately, Central American governments can swing wildly from administration to administration.
