Why are old people so slow mentally speaking
<|assistant|>
Age brings a range of physical and mental changes, including a decline in cognitive processing speed. This decrease in cognitive performance is known as cognitive aging. With less available brain capacity and fewer neuropils, it can take older people more time to complete cognitively demanding tasks and process information. This means that their mental reaction times are slower than when they were younger. Older people may also have trouble focusing and multitasking, which adds to the slower response times. Cognitive exercises and stimulation, as well as physical exercise, are effective ways to help counteract cognitive aging.
