This post cites someone's talk
We started the first mountaineering club at Eton and made dozens of trips to Scotland and Wales... The day we had an opportunity to get to the summit, Bear came down with a virus and didn't go. .. I just look back on Everest as an amazing experience, which I luckily survived. ..
This guy is talking about some kind of history, so, he is using "started", how about "look back"?
one situation where simple present tense is suitable is to state a fact or regularity, such as, the sun rises in the east, I drink 20 cups of water everyday
what is the appropriate situation where I should use the simple present form of "look back"?
