Which tradition of Buddhism is more open to the idea of longevity and healthspan extension?

For a long time I've been really into the space of longevity, both radical lifespan extension through biotechnology and the optimization of quality of life during old age (healthspan extension) through currently available protocols on diet, exercise, sleep, meditation, etc. I'm really interested in the Buddhist perspective on this movement, especially how different schools (Thai Forest, Soto Zen, Plum Village, IMS/IMC, Chinese Chan, Chinese Pure Land, Tibetan Vajrayana, and Sri Lanka Theravada) might perceive it differently. My #1 core value is to live as long and healthy as possible, both physically and mentally. I got into Buddhism, because it seems like a comprehensive and effective framework in supporting individuals' mental well-being, especially during old age. I think that if you are not going to have any children, then you have to embrace some kind of spirituality system to offset the very real and catastrophic effects of loneliness and stress on your health and lifespan. Your mind won't be kind to yourself as you get older, and you have to love something other than yourself to be sane. Which Buddhist tradition do you think is the most compatible with this very new kind of value (life is good and I wanna live as long and healthy as possible) that has emerged in a community only very recently, thanks to technology and urban life enabling such a person? (r/longevity, r/peterattia, and r/Biohackers) Thai Forest, Soto Zen, Plum Village, IMS/IMC, Chinese Chan, Chinese Pure Land, Tibetan Vajrayana, and Sri Lanka Theravada? I know some aspects of Buddhist philosophy are very much contradictory to this goal (think The Five Remembrances in Buddhism, contemplations on impermanence: that we will grow old, that we will get sick, that we will die, that all that is dear to us will change and we will be separated from it, and that our actions are our only true belongings, and we will inherit their consequences). So one of my concerns is that if I'm practicing with a tradition that emphasizes those aspects, it would eventually lead to cognitive dissonance/internal conflicts, creating additional stressors in my life. I know I tend to get very hysterical/neurotic and compulsive about these things, so it's good to give these extra thoughts to it before deciding.
