###Human: What are the physical changes that come with aging? ###Assistant: Hi. At her age, cellular aging can speed up depending on her overall health. If she has any underlying chronic disease or if she has a deficiency of essential minerals and micronutrients, all these can speed up the aging process. However at her age, fatigue or excessive tiredness judging from the fact that she falls asleep frequently, must be evaluated thoroughly. Please provide more details as to whether she has any disease or chronic conditions. Also, let me know if she can sleep at night or if there is any recent history of weight loss, etc. If yes then thorough investigation is needed to rule out any underlying pathology. Please give me more details and get the following investigations done primarily. Revert with more information to a family physician online.--->
