Thoughts- I think, therefore I'm

An old man walked into an art gallery. Ambika and I visited an art gallery to watch Amit's works. I got to know that the old man is Ramesh Thanve, famous educationist walked into the gallery. Amit introduced me as a person from Azim Premji Foundation. Ambika introduced Ramesh Thanve as an educator who worked a lot for early literacy in 1960s. Talking about 1960s and age, he revealed that he's 76. Stumped and surprised by his age, I wondered how he's very active and got energy to walk into art gallery and catch up with his friend. He mentioned a French Philosopher, Rene Descarte. 'I think therefore I am.'
