You see, I am sitting here, deciding if immortality exists?
1) WHAT ARE YOUR THOUGHTS ON IMMORTALITY?
2)DO YOU THINK YOU LIVE A STRESS FREE LIFE
3) HOW OLD DO YOU THINK IT IS POSSIBLE TO LIVE?
4) HOW OFTEN DO YOU SLEEP EVERY NIGHT?
Yes, you notice that I included sleep in this factor? You see, they have studies that show that under 5.5 hours and more the 8.5 hours is bad so 6-8 hours is needed, but 6-7 is ideal, but others such as athletes and people with hypersomnia need more. So it also varies depending on the individual.
