just as effective, according to a new study.<\/p>\n<p class=\"ai-optimize-8\" data-start=\"934\" data-end=\"1169\">Researchers from institutions in Slovenia and the Netherlands found that both regular and decaffeinated coffee produced similar effects on alertness and brain activity, highlighting the powerful role of expectation and routine.<\/p>\n<p class=\"ai-optimize-9\" data-start=\"1171\"
