The senior population around the world is significantly increasing with the expectation that older adults aged 65 and over will make up 16% of the world’s population by 2050 (Global Health and Aging, 2011). This population surge could be the result of a decline in fertility, along with inflation in the population’s maximum lifespan (Global Health and Aging, 2011). Chronic diseases including cancer, diabetes and heart disease are the leading cause of death worldwide, specifically for those aged…
