What is the healthiest daily routine?

I'd like to know what is the most optimal time to go to sleep, wake up, what to eat and when to eat it. Also where would be good to live, what type of altitude and climate. What supplements to take and and types of exercises? What type of bed to sleep in? Would it be beneficial to sleep in a float tank? Hyperbaric chamber? What types of tests should be done and how frequently to ensure you're perpetually in good health? And anything other suggestions would be great.
