Answer: Arnold's risk for coronary heart disease.
Arnold should worry due to the fact that one of the causes of coronary heart disease is the formation of plaque which is made up of deposits of cholesterol and other substances in the artery. Considering his blood pressure was 130/85, his total cholesterol was 210 (LDL was 175 and HDL was 35), it should raise some concern.
The relationship is between negative emotions and the progression of HIV infection. It is said that negative emotions like resentment towards a family relative, fears of death and uncontrolled stress contributes to the increasing of the infection, rather than postivie attitudes may serve as a good antibiotic.
Parents often make the mistake that all their children have close personalities, but in truth, it is not so. For example one child may excel in sports while another boy in the family loves to read or draw and the same goes for the girls. [ There is always a leader of the pack (more than two children) and there will always be some discord, but if they are taught to communicate with each other and with their parents as far as what is right or wrong they will settle in and as they get older they will mature and most get along just fine even if they have their own individual personalities. Some families have a 'Panel' or 'Family Meeting' when there is too much discord and all sit down and discuss the problem and come to some agreement in a calm way. There should also be house rules and all the children should have chores to do around the house. ]
