Do you think that our genes can affect our health? how?

Of course, it can affect our physical and mental health. For one example, if one parent is overweight, there's a chance that the child would be overweight, or another example is that if one parent is bipolar,or have some other mental illness, there's a chance that the children will have the gene, and devolp the illness. This is the same way with major illnesses and cancer.
