The elderly people are of intrinsic value to societies. Their health is Africa’s wealth. Unfortunately, Africa has serious health burden raging from diseases, poverty ignorance that hardly support healthy ageing. Development indicators from World Health Organization and the World Bank provide glaring evidence that Africa countries are far behind other regions of the world in health conditions of the citizens. This paper discusses the benefits that accrue from having a healthy old age population. Such includes poverty reduction, stress free ageing, assisting in taking care of young ones. It examines the role of information in enhancing healthy ageing in Africa. …

It is well established that ageing handicaps the ability of prey to escape predators, yet surprisingly little is known about how ageing affects the ability of predators to catch prey. Research into long-lived predators has assumed that adults have uniform impacts on prey regardless of age. Here we use longitudinal data from repeated observations of individually-known wolves (Canis lupus) hunting elk (Cervus elaphus) in Yellowstone National Park to demonstrate that adult predatory performance declines with age and that an increasing ratio of senescent individuals in the wolf population depresses the rate of prey offtake. Because this ratio fluctuates independently of …
