What’s said in this shiur
The opening of this shiur, in Rabbi Daniel Glatstein’s own words— taken from the captions, so names and Hebrew terms may be approximate.
Do you take omega-3 every day? You know, omega-3 could really prolong your life. Also, flaxseed oil. Flaxseed oil is great. >> [music] >> It really is a a great life extender. What about whey? Whey protein really gives extension to one's stay in this world. What about exercise? Do you make sure to exercise at least 30 minutes every day? You know, there's a lot of things that a person could do to [music] preserve and ensure long life. But none of the above is [music] the most important. It's not omega-3. It's not exercise. It's not flaxseed oil. The most important [music] thing that we could do to extend our stay in this world is what David Hamelech teaches us. David Hamelech says, "Mi ha'ish ha'chefetz chaim?" Who is the man who desires life? "Netzar netzar l'shon ch'veira." [music] Guard your mouth from evil. Be careful with the words that you say. You know, the Gemara tells us about Rav Alexandri [music] who went out into the street. He says, "Man boi chayei? Man boi chai?" Who wants life? Who wants life? And everyone came running to him.
