"Among all our casual topics, whether someone likes the taste of beer is the single best predictor of if he or she has sex on the first date." "If you want to know... Is my date religious? Ask... Do spelling and grammar mistakes annoy you? If your date answers 'no'—i.e. is okay with bad grammar and spelling—the odds of him or her being at least moderately religious is slightly better than 2:1." - Simon
