And it may have <br/><br/> been caused by mental fatigue.<br/><br/>M: I don't think it's so serious. <br/><br/>No. 2 Lottery ticket<br/><br/>M: Three ... four ... one. Oh, no! I lost again! That's the fifth<br/><br/> time this month!<br/><br/>F: How many numbers did you get this time?<br/><br/>M: Only three. This is the last time I bought a lottery ticket. <br/> ( Q.
