Increasing lower leg muscle mass can be as easy as a set of slow squats in your kitchen. Accelerated results can be obtained by adding resistance (weight).

After decades of testing cars almost exclusively on male-modeled dummies, the federal government just rolled out the THOR-05F will be the first high-fidelity crash test dummy designed to actually represent the average adult woman.

For context: the old “female dummy” was basically a scaled-down male dummy, not an anatomically accurate model. That meant seatbelts, airbags, and car frames were optimized around male bodies, leaving women at higher risk in real-world crashes.

Women are significantly more likely to be seriously injured or killed in the exact same crashes as men — partly because the test data never accounted for differences in pelvis shape, torso mass distribution, neck strength, or seating position.

The THOR-05F includes 150+ sensors, capturing detailed injury patterns in the head, neck, chest, abdomen, and lower body. These are areas where women often experience worse outcomes.

It’s designed to improve testing for modern crashes, like side-impacts and angled collisions, which are especially dangerous for female occupants.

It’s taken far too long, but this is a big step toward closing a very real, and very deadly, gender safety gap.

The te**es are one of the most immune privileged places in the entire body.

They’re specially protected because s***m develop after your immune system is already formed.
To immune cells s***m look “foreign” so without extra safeguards the body might accidentally attack them.
To prevent that the te**es create a tightly controlled, low-inflammation environment:

The Blood–Testis Barrier

Sertoli cells form one of the strongest barriers in the human body physically separating developing s***m from immune cells.

Sertoli Cells

They not only nourish developing s***m, but also clean up debris and reduce immune alarm signals that could trigger inflammation.

When this protective system is damaged through trauma, infection, torsion, or surgery the immune system can suddenly "meet" s***m for the first time and react strongly. This can lead to things like anti-s***m antibodies or autoimmune orchitis, both of which can impact fertility.

Cytolysis is what happens when a cell bursts open because too much water rushes inside. Cells constantly balance water and solute levels, if they’re placed in a very hypotonic environment, water floods in. Pressure builds… and eventually the cell membrane can’t hold it anymore.

Knowing a bit of anatomy might just save your relationship!

Extension of the fertile window (the number of days an egg can be fertilized) has led cheating allegations and cases of questioned paternity.

But s***m really can be stored in a woman’s reproductive tract for up to a week (usually more like 3-5 days, but extremes exist).

Chlorophyll The Pigment That Powers Life

Chlorophyll is the green pigment inside plant, algae, and some bacterial cells and is the reason our planet looks so green. It Captures sunlight and turns it into usable energy through photosynthesis.

What Chlorophyll Does:

Absorbs sunlight (especially red & blue light)

Helps convert light energy into sugars plants use for fuel

Gives leaves their green color

Supports oxygen production

It’s structurally similar to human hemoglobin, both have a ring shaped structure, but chlorophyll has magnesium in the center, while hemoglobin has iron.

Chlorophyll molecules have a magnesium atom at their center. Without magnesium, plants literally can’t photosynthesize!

The Why of SCI

Many ask why I went into massage therapy. While that answer is complicated, it has a lot to do with being able to help my wife. She injured her back at work, and it was supposed to be a quick fix, easy p*ezy. She was young, active, and healthy.

What followed was nearly a decade of, doctors, surgeries, PT, OT, a laundry list of medications, alternative treatments, painful procedures, blatant quackery from both western and alternative medicine. At multiple points, both my wife and I seemed to be at the end of our respective ropes. The experience tried our relationship in every possible way.

In the end, it was the integrative approach of Mayo Clinic’s Pain Clinic that brought her back. I can still remeber the first day I saw her dancing again. It made me cry. It was wonderful. It’s certainly wasn’t easy and we learned that with chromic pain there is no “cure”.
