Si-s would probably care more about Ni when it comes to war on their country.
From what it appears that some countries utilise Ni more than others and I think Sweden and Germany nurture Ni more than most which gains them an edge in technology and future economics.
Oh yes, and, alcohol doesn't really harm neurons as much as the dendrite connections at any age. Excessive drinking leads to damaged dendrites which leads to slower motor and mental responses over a prolonged period of heavy drinking. When longevity is linked to alcohol the centenarian who drinks will normally only drink half a glass of wine or half a glass or beer or one shot of liquor a day which is much less than the average drinker.
