There was a time I ate fast food five and sometimes six days a week, but then I ran Mickey D's for 22 years and there was no going out and to where, another fast food operation? Still if it caused any cognitive issues how would I know, people have been calling me crazy(among other things) for decades. Now I just don't have the desire to buy fast food none of the burger chains food tastes the way it used to, okay BK was always bad and the exceptions are In-N-Out and small mom and pop. But then I can't say I have really enjoyed the food at a actual restaurant in a long time either.
