This seems like a simple question but I have no idea where to look for an answer.
As a male, can anything you do increase the chance of genetic abnormalities in your offspring? Can bad diet, smoking, drinking, overwork, drugs affect the DNA in your sperm?
I was reading about the baby Kaylee case (girl with a life threatening genetic condition). Her father also has a genetic heart problem. Assuming he came from England, and considering the conditions in 19th century England - appalling diet and sanitation - got me thinking about whether all those immigrants back then brought a crop of health problems for our future.
