In general if you hear five people a day tell you how "X changed my life!!1" it's probably bullshit mixed with a pinch of placebo.
Want to have a good life and be healthy? Spend more time outside, avoid long commutes, take long breaks, do things you like doing whenever possible, value yourself and your time, and don't take shit from people. This way even if you do die young, you'll die with a smile.
