"1. Exercise regularly: Regular physical activity can help improve your overall health and wellbeing. "

"and certain cancers. Aim for at least 150 minutes of moderate-intensity aerobic exercise or "
"75 minutes of vigorous-intensity aerobic exercise per week, along with muscle-strengthening "
"activities at least two days per week.\n"
"2. Eat a balanced diet: Eating a balanced diet that is rich in fruits, "
"vegetables, whole grains, lean proteins, and healthy fats can help support "
"your overall health. Try to limit your intake of processed and high-sugar foods, "
"and aim to drink plenty of water throughout the day.\n"
"3. Get enough sleep: Getting enough quality sleep is essential for your physical "
"and mental health. Adults should aim for seven to nine hours of sleep per night. "
"Establish a regular sleep schedule and try to create a relaxing bedtime routine to "
"help improve the quality of your sleep.")

"Non-renewable energy sources, on the other hand, are finite and will eventually be "
"depleted, such as coal, oil, and natural gas. Here are some key differences between "
"renewable and non-renewable energy sources:\n"
"1. Availability: Renewable energy sources are virtually inexhaustible, while non-renewable "
"energy sources are finite and will eventually run out.\n"
"2. Environmental impact: Renewable energy sources have a much lower environmental impact "
"than non-renewable sources, which can lead to air and water pollution, greenhouse gas emissions, "
"and other negative effects.\n"
"3. Cost: Renewable energy sources can be more expensive to initially set up, but they typically "
"have lower operational costs than non-renewable sources.\n"
"4. Reliability: Renewable energy sources are often more reliable and can be used in more remote "
"locations than non-renewable sources.\n"
"5. Flexibility: Renewable energy sources are often more flexible and can be adapted to different "
"situations and needs, while non-renewable sources are more rigid and inflexible.\n"
"6. Sustainability: Renewable energy sources are more sustainable over the long term, while "
"non-renewable sources are not, and their depletion can lead to economic and social instability.\n")
