it may be wrong to live this long though... i've been thinking and i see now that a fruit fly has a 24 hour life because who ever is reincarnated into one need the least amount of time in that body. so when we become human since my belief that its all about becoming enlightened it doesn't matter how long we live. people are living to be older in america but sadly america is just such a corrupt country. the society is so corrupt it makes sense why america has the most crime and the most prisoners. prisoners = people rebelling against the way a society and culture is. and sure if we live till 100 we can learn a whole lot but sometimes someone could just be brought back into more illusions. like a old person whose been in fear till they were 100. also if humans made a serum to make someone live to 1000 that person would probably commit suicide before he turns 1000 because life is suffering. the reasons why we die is because we are purified over and over again into a new life form.
No lies there, it's hard attempting to stay pure in a contaminated world. Only thing I can tell you is to do what you can. Contamination is everywhere and the people are causing it and not thinking twice about it. See the problem with people, they don't like to fix mistakes, they like to ignore them and hopes that they fix themselves which never happens. This is one of those 'have to learn the hard way' type of things, like global warming. Ultimately mankind will have to answer for their misdeeds even though it won't be for a while.
As for you, continue to do what you can as I mentioned. Use water purifiers, buy healthier foods even though they've been through chemical alterations. See that's the thing, in this world there's not much you can do but to go with the flow unfortunately but at least by making good choices you can whether the storm. May you live a long and happy life for making the right decisions.
Just do whatever you can... Exercise. Cut out as much meat and dairy as you can. Fish is still pretty good. But go for rice or almond milk instead of regular milk. And seitan is a great meat substitute.
I think you have all the right ideas already, you just need the budget to live healthily. Eat trusted organic labels, don't use toothpastes with fluoride, and do your part to recycle, reuse, garden, and definitely write to your lawmakers to express your opinions. Albuquerque, the city I live in, recently changed their water laws and now we won't have fluorine in our tap water ! The best we can do is try our best. I don't want fluoride to calcify my pineal gland, toxins from processed foods to make up any part of my body, nor even waste to be "produced" by me only because I'm buying something. I'd rather the world not be at all like it is. I don't know why people get so hostile at those of us who think this way. Such weird creatures humans can be.
