In a future study, it is recommended that more subjects of both sexes be chosen; that meals of known cholesterol content are prepared for the subjects and that their compliance with the dietary regime be monitored effectively; and that each subject acts as his/her own control by consuming both diets in a randomised, cross-over sequence. Even then, any conclusions pertaining to the influence of dietary cholesterol on plasma cholesterol concentrations would be limited to Caucasian, middle-aged omnivores.
2. Negativity definitely creates more conflict. As Student #1 writes, negative people tend to see everything as a conflict. I have a neighbor who is extremely negative and it has created constant conflict in her relations with herself, her family, and her friends (and her neighbors!). For example, she found conflict when my husband was blowing snow from our driveway (when, if she had been quiet and not created a problem, he would have cleared her driveway…instead, by yelling at him to be careful and not blow snow on her driveway, he got upset and angry which resulted in him not wanting to help her).
