1. Quit smoking and drinking: Long-term smoking and excessive drinking are linked to various cancers, including lung, liver, breast, stomach, and colon cancer. Additionally, they increase the risk of high blood pressure, diabetes, coronary heart disease, and stroke in older adults. 

2. Adopt a light diet: A low-salt and low-fat diet is recommended for seniors with chronic cardiovascular diseases.

Excessive salt intake raises blood pressure, while high-fat consumption worsens atherosclerosis. A balanced, nutritious diet that includes proteins, micronutrients, vitamins, and dietary fiber is important. 

3. Maintain a regular sleep schedule: Disrupting the body's circadian rhythm through irregular sleep patterns can lead to hormonal imbalances and weakened immune function.

It is crucial for older adults to establish a regular sleep routine and aim for at least 7 hours of sleep each night. 

4. Cultivate a positive mindset: Maintaining a positive attitude can improve one's luck and overall well-being. People with negative personalities or constant anxiety and depression are more prone to various cardiovascular diseases and cancers.

After reaching the age of 60, there is no need to worry excessively or be anxious, as they have likely experienced many challenges in life.
