False I think hope this helped
What I do for the pain to go away is: put ur hand into a sort of C shape, place ur hand on ur arm, in the middle starting next to ur elbow, then use ur thumb and top fingers to squeeze (but not too hard) all the way down to the tip of the middle finger. This process will relieve stress and soreness. If u need a medicated cream to make it slippery, that may also help while massaging.
A. A person can inherit a tendency toward a mental disorder.
In terms of heredity, this would be the best answer. Because heredity refers to biological factors, inherited through genetics of parents and relatives. Not always will that person develop a mental disorder due to a biological relative being diagnosed with a mental disorder, but it is possible and a high risk factor. The death of a loved one, using drugs or alcohol, and being neglected during childhood are more of environmental and psychological factors.
Hope that helps. :)
