How fatigued certain activities make an older person feel can predict the likelihood death is less than three years away, according to research published in the Journal of Gerontology: Medical Sciences by University of Pittsburgh epidemiologists.

Older people who scored the highest in terms of how tired or exhausted they would feel after activities were more than twice as likely to die in the following 2.7 years compared to their counterparts who scored lower.
