This article is filled with lots of great recommendations that I agree with-a few tidbits do not apply to those with IC, but, the bulk of it is widely applicable and much of what I recommend.

I think this is a great read on not only aging, but, just overall wellness. And, if you are a patient and understand my philosophy, it gives a lot of support to some of the fundamental causative factors of IC. http://www.huffingtonpost.com/dr-mercola/if-you-want-to-age-gracef_b_700335.html
