Recent analyzes suggest that maintaining a healthy lifestyle can offset over 60% of the “lifespan-shortening” genes you may have inherited.
The study, published in the BMJ Evidence-Based Medicine Journal, also suggests that an unhealthy lifestyle increases your risk of death by 78%, regardless of whether you have good or bad genes.
Although the study was observational and not conclusive, scientists believe there are four components of an optimal, healthy lifestyle: These are smoking cessation, regular physical activity, getting a good night's sleep, and eating a healthy diet.
Between 2006 and 2010, over 350,000 participants (all of European descent) were recruited for multi-study analysis through UK Biobank, a large biomedical database and research resource.

According to the Centers for Disease Control and Prevention, participants were given a weighted lifestyle score and a polygenic risk score, which calculates an individual's disease risk based on their genes.
The participants' health status was tracked until 2021, according to the analysis. During this period, 24,239 of the participants died.
Researchers said people who are genetically predisposed to live shorter lives are 21% more likely to die early than those who are genetically predisposed to live longer, regardless of their lifestyle.
Additionally, participants with a higher genetic risk for a shortened lifespan and unhealthy lifestyle were genetically predisposed to live longer and were less likely to die compared to participants who maintained a healthy lifestyle. He said it was twice as expensive.
Researchers say people with a high genetic risk of shortened lifespans could add nearly 5.5 years to their lives by making healthy lifestyle changes at age 40.
The study's researchers classified premature death as dying before age 75. According to the CDC, the average life expectancy for Americans is 77.5 years for both men and women, and 80.2 years for women.
