An estimated 40% of seniors are chronically underhydrated, and adults ages 65 and older have the highest hospital admission rates for dehydration. The main problem is that the sense of thirst diminishes with age. In addition, many people are not mindful about drinking water over the course of the day. People can increase their intake by setting up drinking routines, jazzing up drinking water, and increasing their intake of water-rich foods.

Science continues to find that people with an optimistic outlook enjoy healthier and longer lives. The power of optimism is not just having a sunny disposition, but applying this mindset to make positive change.

Five blood tests beyond basic blood work may be worth pursuing for older adults. For example, a test to determine one’s vitamin B₁₂ level might be helpful, since older adults sometimes have trouble absorbing that vitamin. Likewise, older adults have less ability to absorb sunlight through the skin, which may lead to less production of vitamin D. Other blood tests to consider include those for HIV or hepatitis C infection, and a test to measure fasting blood sugar.
