So what causes aging?

Doubt on aging gene
According to the initial study, oxidative stress, a proposed culprit in mitochondria’s mechanism of aging, did not seem to be a factor in aging. The aging process is affected only by caloric restriction, and oxidative stress actually decreased. But it does seems like it's not true after all. Incidentally, animals that breathe slower lives longer as well.
