A doctor could affect a person's lifestyle through; for example:
Work does affect lifestyle, because it could make you so busy that you can't sleep well or you can't hang out with friends. It could affect your mood and you will feel a lot of pressure. That, of course, does not mean you shouldn't work.
Yes, sometimes some people in your life could affect your lifestyle choices, but, if you feel it is wrong or you have a plan for the future then you are in complete control of the choices you make as to whom you hang around with.
a cigarette effects the mood because it could effect the brain of someone by chemicals
Socio-economic factors are all to do with costs. Socio-economical factors that could affect the access to complementary therapies could be that persons may not be able to afford them, although some complementary therapies are referred by the doctor, if the person doesn't want to/can't wait that long, they would have to pay this might make it a problem for those who cannot afford it.
You would want to consult your doctor. Your body could need different supplements due to what kind of lifestyle you lead.
You could do a survey or ask people you know to choose a piece of food out of a group of different coloured foods
No vampires tend to keep a normal lifestyle and tend to not bring up situations that could possibly expose them for what they really are.
(i am not a doctor or anything) but if there is dangerous mold or mildew this could worsen a persons athsma, but athsma can not be an effect of the bad conditions of a house.
If you have dehydration, you become lightheaded and sometimes black out so it could make you lousy in the sport or the sports training.
A thermometer can tell a doctor if a person has any changes in body temperature. If a persons temperature is high it could mean they have some type of infection.
I think it is certainly possible, but you need to discuss this with your own doctor.
An example: Let's say you had a bad disease that was curable only if treated in the first week. Now let's say you had unreliable information, say, your doctor said you were fine. So in seven days you pass from curable to incurable. Understand?
