getting older

My aunt is getting older in a way that is not hm accepted nowadays? She is becoming more and more dependant- she needs support otherwhise she will live but the quality of her lif is getting lower and lower. I visited her last week and at first I was shocked - for a time being everyone was and is fit in my family. Ok my grandparents get older and older still they can do many things alone- my grandma is even using laptop and internet - thx to her the university has its web page, they both use mobiles and then u see a person who is younger than them but who is phisically and mentally much older than them. What woulde be our thoughts? mine were mixed from confusion how come and why this things happen and we cannot prevent them, through feeling guilty why for me as young person it is so hard to find patience and power to interact more with elderly till thought how current society becomes not supportive for the family.
