Reaching 100 years may seem like an extraordinary milestone, but Dr. Gareth Nye, a Biomedical Science lecturer at the University of Salford, believes it’s achievable by following four key rules. While genetics influence about 20-30% of your lifespan, lifestyle choices play a significant role too—meaning your actions can improve your odds of living longer.
Dr. Nye stresses that longevity isn’t about intense workouts but maintaining a consistently active lifestyle. Instead of structured exercise programs, he recommends increasing daily activity levels and avoiding long periods of sitting. Simple adjustments like using standing desks or walking during your commute can make a big difference. Supporting this, recent studies reveal that walking up to 10,500 steps daily can reduce early death risk by 39% and lower heart attack or stroke chances by 21%. Regular brisk walking or short bursts of high-intensity activity can also reduce dementia risk by up to 40%.
Diet is another cornerstone of longevity. Dr. Nye urges avoiding alcohol, tobacco, saturated fats, and highly processed foods rich in preservatives. Instead, opt for minimally processed meats and plenty of vegetables, preferably organic or free-range. Limiting added sugars and excessive salt intake is crucial; most people consume far beyond the recommended sodium levels, exacerbating cardiovascular risks. By diversifying your intake of fruits and vegetables—fresh or frozen—you can support long-term health and reduce disease risks.

Getting quality sleep is equally vital. Research shows that 7 to 8 hours of uninterrupted sleep each night correlates with the lowest risk of premature death. Sleeping less than 7 or more than 8 hours daily has been linked to increased health risks, including dementia, which currently affects nearly one million people in the UK. Maintaining steady sleep patterns will help optimize longevity benefits.
Finally, knowing your personal health risks through regular medical check-ups and genetic testing can provide valuable insights. Since genetics account for a portion of life expectancy, understanding predispositions allows for better prevention and early intervention. The NHS advises that genetic testing might reveal important health-related information for you and your family, facilitating informed decisions on managing potential conditions.
By embracing these four simple rules—increased daily activity, mindful eating, quality sleep, and health awareness—you can significantly enhance your chances of enjoying a long and healthy life.
