Seven longevity biomarkers to track.

Last year, I wrote about ten of the most interesting predictors of longevity.

Many of them were subjective, but as we all know, the objective physiological processes that occur in the human body also predict how long we live.

Luckily, we can measure most of them.

Some are standard at doctor's checkups.

Some require more involved and expensive testing.

Some you can complete yourself at home with simple household objects.

But if you care at all about how well you're doing in the longevity game,

it's worth paying attention to some of them.

Number one, triglyceride to HDL ratio.

Also known as the orthogenic index of plasma, a high triglyceride to HDL ratio is one of the best indicators of one's risk for heart disease.

It has the added benefit of predicting lipoprotein particle size and insulin resistance.

These all impact a person's longevity. It's difficult to live long when you're getting heart

attacks and your insulin skyrockets if you even glance at a potato. Sure enough, an elderly woman,

the T to HDL ratio predicts all-cause mortality, not just cardiovascular mortality.

A ratio of 2 or under is good. Anything above should be addressed before it worsens.

And anything above 4 means trouble.

Number 2. Sex hormone status.

Our bodies use them to build tissues, build babies, and lead

robust, meaningful lives. Evolution is mostly concerned with propagation of the species, with
