Oh yes. That’s what I do all the time:)
Early dinner, home made food, vegan whole food plant based diet, avoiding sugar, dairy and wheat, avoiding anger and criticising, good sleep hygiene, regular physical activities, pranayam, loud laughters,some form of meditation, good simple companies, self help book reading, some passion in life and avoiding over thinking/ judgements.. these my key recommendations. I try to do these as well.

Lastly, One should also consider why should one live longer & at what cost to nature? 😊
