Why are old people so slow mentally speaking
<|assistant|>
The process of aging can lead to physical, physiological, and cognitive changes which can result in reduced reaction time, reduced information processing speed and difficulty with multi-tasking. Additionally, age-related declines in cognitive and visual functions can lead to decreased abilities for problem solving and decision-making. As a consequence, older people can be perceived as slower mentally.
