Big hands big feets

Never heard about SAD, just looked into it, I stand corrected indeed. Western diet ? I think diet in most western countries isn't as terrible as in USA, although ofc we eat too much processed sugar. Why are USA so much into SAD btw ? I don't understand the history behind this.

Whatever your excuse, USA system is lame for a developed country. Now even chinese people have a better life expectancy than Americans. Pityful

USA has the wors system. Expensive and inefficient.
