Warm greetings to you @safdarali, hope you are doing good. While reading your entry, I realized that you are scared of aging. Being concerned about the challenges that aging comes with, is different from being scared of actually aging. I am not scared of aging, however I am concerned about the limitations it brings along.
Your worries are financial and socialization. I do not know about Pakistan so well, but in my country, we regard and care for our elderly well enough. It is terrifying to wonder if anyone will be there, but it becomes assuring if you know people will be there when you are helplessly aging. Walks, strength exercises and yoga are good combinations for keeping fit while aging.

Thanks for sharing
