Here is an excerpt from a medical journal
Binge and heavy drinking may trigger a long-lasting genetic change, resulting in an even greater craving for alcohol, according to a Rutgers-led study in the journal Alcoholism: Clinical & Experimental Research.
“We found that people who drink heavily may be changing their DNA in a way that makes them crave alcohol even more,” said Distinguished Professor Dipak K. Sarkar, senior author of the study and director of the Endocrine Program in the Department of Animal Sciences at Rutgers University-New Brunswick. “This may help explain why alcoholism is such a powerful addiction, and may one day contribute to new ways to treat alcoholism or help prevent at-risk people from becoming addicted.”
Yogis have maintained that our thoughts shape the body. This is especially true for future births. Our thoughts often match the thinking of the parents where we are to be born. Moreover, since our inner consciousness is more alive than our outer thinking, it registers every reaction we have and deep down knows all the bad karma we did, it further shapes where we are born. Thus future parents and appearance is shaped in a complex pattern based on karma and thinking.
This article shows how the pattern of thing can actually shape even our current DNA!
