In regards to the given topic, today, I am going to talk about Mr. Teg Singh who is a grandfather of mine.
I have been living with him since my birth.
If I talk about his physical appearance and personality, though he’s in his early 70s, he is physically fit and active.
Mr. Singh is not only tall but also quite handsome.
What I like the most about him is that he always dresses up to nines.
Frankly speaking, Mr. Singh is arguably the most kind and helpful person I’ve ever met.
It’s a matter of couple of months back, due to the corona pandemic, my country was in a state of lockdown.
Many businesses had shut down and some were at the verge of extinction.
Nevertheless, medical field was booming at the same time.
Instead of saving people’s life, most of the hospitals were minting money.
Poor people were struggling for even getting the basic treatment.
Seeing this unfortunate situation, Teg decided to offer free medical treatment to people.
He turned his big yoga practice hall into a hospital, where needy people were provided with not only medication but also food.
Even he taught some breathing exercises as well as home remedies to boost the immunity.
Obviously, at first, I was nervous and afraid, but after seeing his dedication and determination, I really felt proud on my grandfather.
I couldn’t stop myself to be the part of the crew.
It was a proud moment to see, unlike others, without even charging a single penny; he saved the lives of more than 100 people.
