Farmer doing Phd.

Today I heard a news that a 70 years old farmer is doing Phd in Pakistan.His name is Mushtaq Ahmad and he lives in gujranwala. He is a father of 8 childrens. Before this he completed his M phil last year. But Still he is a farmer and he daily works in his fields. He says that he is studying not for the sake of job but to be an Example.He can read, write and also speak English Language. If you see that Man then no one will believe that this man who is 70 years old can do Phd. Its a good news or us that still there are many hard working people in this country.
