This is because gold is very resistant to bacteria. Bacteria are microscopic single-celled organisms. Bacteria are prokaryotes‚ meaning the entire organism consists of a single cell with a simple internal structure. The DNA of a prokaryote is neatly packed in the nucleus. The bacterial DNA floats freely in a twisted threadlike mass called the nucleoid. Gold is unaffected by almost everything. The only materials that can affect gold are man-made. Since bacteria are a natural organism‚ it cannot react

Physiological arousal has been theorized to affect size perception in prior research (Geuss‚ Stefanucci‚ de Benedictis-Kessner‚ & Stevens‚ 2010). Geuss’s team of researchers employed jogging in place as well as counting backwards by sevens to induce physiological arousal in a subject‚ each in a different experiment of their 2010 study. Both continually jogging in place and counting backwards by sevens were found to induce physiological arousal (2010); the arousal level was measured using heart rate
