Continuing from #9, remember that it is important to be optimistic, but you have to be careful not to overdo it and think that everything is peachy. This finding was revealed in a study by Frieder Lang, PhD, who found that older people who have a way-too-positive outlook on life will suffer from a lot of disappointments, which will lower their quality of life. “Pessimism makes you more conscious, whether it’s about your health or about following instructions,” says Frieder, and that’s why we have to be moderate in our optimism, particularly at an advanced age.
