talk of wisdom from a 90 year old man

i have been seeing this patient for 2 weeks and i noticed that he rarely talks and very observant. 

he would always mention that i feel bad for this generation, i was assuming he was just having bouts of dementia..

one day, i finally had a good conversation with him, i asked him what he meant by feeling bad for this generation..he explained that my generation always worry of the future and the past..he mentioned that he had been telling his kids for 40 years now to not worry of the future and the past..

so i finally asked him: how do you do that?

he answered to aLwAys “LIVE BY THE MOMENT, always appreciate everyday because everyday is a future and will be past” he continued by saying if you follow that, you will never have regrets in your life…
