For anyone interested, there's a tool http://www.aging.ai which does exactly that, using deep-learning algorithms on, and I quote, "hundreds of thousands anonymized human blood tests".

I've used it myself for fun after doing a blood test. It's a free alternative to InsideTracker's InnerAge product.

Wow very cool tool! I didn't know about this somehow. Thanks for sharing. Cool that you've tried it on yourself.
