Hey @manisha.jain9, how is India today? After reading your entry, I love the way you set your goals towards learning throughout the phases of life and doing good. Just like you, I do not fear old age, I rather prepare for the challenges that comes with it. Nuts are very rich in vitamins as well as vegetables and fruits, these are good nutritional items you listed. Squatting and walking are perfect for the body's build up, even for the young.

Thanks for sharing
