My Mom lived to 101.
She never drank alcohol, coffee, nor smoked.
She had a normal diet, meat, fish, boiled veggies and potatoes type. She loved baked goods, a never avoided fatty meats. Gene wise, he parents had a normal life span (80s).
She had a good sense of humour, listened to music a lot, didnt watch tv, never paid attention to the daily (bad) news. Her mind was quite good to near the end.
No idea what her secrets was. Maybe the luck of the draw.
