God, to prevent all escape, hath sown the seeds of death in our very constitution and nature, so that we can as soon run from ourselves, as run from death. We need no feller to come with a hand of violence and hew us down; there is in the tree a worm, which grows out of its own substance, that will destroy it; so in us, those infirmities of nature that will bring us down to the dust.
