Here’s my personal advice – do what feels right. If you truly believe in something, do it with all your might. Science actually invalidates one individual’s experiences and can only generalize based on large population studies. Since everyone responds differently, your only way to know whether or not it’s going to work is to try it (within reason, of course). Rather than trying to exclude the placebo effect that most studies try to do, take advantage of your body’s natural ability to heal itself, no matter which option you choose.
However, realize that that one pill, supplement or exercise regimen is not going to make you younger. Eventually, something will work for you, but without changing your mindset and daily habits, your health problems will return and you’ll be back to square one.
For some reason he reminds me of Doctor Pai. I don't know why. Maybe it's the tie?
