Do you get happier as you age? I think you get more experience, you get more wiser. I'm 52 now. I still feel I haven't reached the peak of my mental and physical endurance. I still ran 170 km last week from Chennai to Oruville to attend a marathon. So I'm still feeling pretty good at this age. You think you're getting physically better? Yeah, I think physically you're getting stronger. So it's not about sprint, right? You might be good as a sprinter in your 20s and 30s, but when you are older, you become better at endurance. When you want to push, say, run ultra races for 40 hours, two days, two nights, nonstop running, you're much more stronger, your body, after a couple of decades. Also your mental endurance is so much stronger than somebody half of your age.
