Depends on what you want out of life. I eat a fair amount of healthy stuff but I also eat fried xhicken, chicken wings, plenty of sweets, etc. I’m not going to deny myself small pleasures on the offchance it let’s me live a bit longer.
That said, I also don’t want to basically be suffering for the last 10 years of my life. If it gets that bad, maybe I’ll just end it myself.
