Explanation:

1. Long - lived grandparents: Genetics play a role. Long - lived grandparents may pass on genes associated with longevity. Also, family lifestyle and health - promoting behaviors could be shared.
2. Weight and lifespan: Obesity is linked to various health problems like heart disease, diabetes, etc., which can shorten lifespan. Underweight can also be a sign of underlying health issues.
3. Cigarette and life - loss: Scientists likely study large populations, track smoking habits and mortality rates, and use statistical methods to estimate the impact of each cigarette on lifespan.
4. Breakfast importance: Breakfast provides energy after an overnight fast, kick - starts metabolism, and can improve cognitive function. It may not be objectively "more important" than lunch or dinner, but its role in starting the day is emphasized.
5. Exercise in youth for long life: Exercise in youth helps build a strong cardiovascular system, muscle mass, and bone density, which can contribute to overall health and longevity.
6. Personality and lifespan: Some studies suggest that positive personality traits like optimism may lead to healthier behaviors (e.g., better stress management, more social support), which can impact lifespan.
