6 Which two fat patterns were linked to the greatest brain harm?

• Pancreatic-predominant fat and the skinny-fat pattern
  

  The pancreatic-predominant and skinny-fat profiles showed the most severe loss in brain volume and structure. Learn more.

• Balanced high fat and balanced low fat profiles
• Liver-predominant fat and the lean reference group
• Subcutaneous fat and general abdominal fat storage

7 What type of device has been shown to improve heart cell renewal?

• External pacemaker patches
• Left ventricular assist devices
  

  Left ventricular assist devices (LVADs) reduce the heart’s workload, allowing cardiomyocyte renewal rates to rise significantly. Learn more.

• Wearable blood-pressure monitors
• Implantable rhythm stabilizers

8 Which pesticide has been linked to a significant increase in Parkinson’s disease risk?

• Malathion
• Chlorpyrifos
  

  Long-term chlorpyrifos exposure is associated with more than a 2.5-fold higher risk of Parkinson’s disease. Learn more.

• Atrazine
• Carbaryl

9 What condition develops when minerals in urine crystallize and form hard deposits?

• Bladder infection
• Urinary retention
• Kidney inflammation
• Kidney stones
  

  Kidney stones form when concentrated minerals crystallize and clump into solid deposits in the urinary tract. Learn more.

10 What daily habit helps reduce serotonin-driven bone loss?

• Fasting long hours for several days
• High-intensity workouts every two days
• Heavy protein at night to protect against bone
• Regular sleep and steady meals
  

  Stable routines — sleep, meals, and proper digestion — lower stress chemistry and reduce excess serotonin signaling on bone. Learn more.

11 How many Americans live with some degree of kidney dysfunction?

• 35 million
  

  Chronic kidney disease affects 35 million Americans and more than 800 million people worldwide, making it a major global health burden. Learn more.

• 5 million
• 12 million
• 2 million

12 What problem develops when vitamin D drops too low?

• Swelling in the sinuses while you sleep
• Weak muscles that hold the airway open
  

  Low vitamin D reduces the strength of throat-stabilizing muscles, allowing soft tissue to collapse inward and create the airflow vibration that becomes snoring. Learn more.

• Faster breathing during sleep
• Extra tissue forming in the throat

13 How many points of variation commonly occur in blood pressure readings?

• 5 points
• 8 points
• 14 points
  

  Blood pressure can vary by roughly 14 points at the peripheral sites where it is usually measured, contributing to frequent misdiagnoses. Learn more.

• 20 points

14 Which herb used in Traditional Chinese Medicine (TCM) for over 2,000 years is now being studied for aging support?

• Astragalus
  

  Astragalus root has a long history in TCM and contains compounds that affect oxidative stress, inflammation, metabolism, immune balance, and telomere maintenance. Learn more.

• Ginseng
• Goji berry
• Schisandra

15 What irrigation source may contribute to the spread of antibiotic-resistant contaminants?

• Collected rainwater
• Natural spring runoff
• Mountain reservoir water
• Recycled wastewater
  

  As global water shortages grow, recycled wastewater is used on over 20 million hectares of farmland in 50 countries, yet treated water can still carry pathogens and resistance-related contaminants. Learn more.

16 Why isn’t plain water enough after sweating heavily?

• Water alone doesn’t replace electrolytes or support fluid retention
  

  Sweating removes electrolytes, and without them water is absorbed poorly and lost quickly, limiting endurance, focus, and coordination in the next workout. Learn more.

• Water prevents carbohydrates from being stored as muscle fuel
• Water blocks protein absorption during early recovery
• Water slows the cooling process needed for muscle repair

17 Which tattoo ink ingredient can break down into compounds that damage deoxyribonucleic acid (DNA)?

• Nickel
• Chromium
• Azo dyes
  

  Azo dyes can degrade into aromatic amines, chemicals known to damage DNA and raise cancer risk when inks are exposed to sunlight or laser removal. Learn more.

• Cobalt

18 Which benefit is not associated with caring for grandchildren?

• Stronger social bonds
• Higher cortisol levels
  

  Caring for grandchildren lowers cortisol and boosts neuroprotective compounds, supporting healthier memory and brain function. Learn more.

• Greater sense of purpose
• Release of brain-supporting compounds

19 Why is the Homeostatic Model Assessment of Insulin Resistance (HOMA-IR) useful for early detection?

• It needs only fasting glucose and fasting insulin
  

  HOMA-IR works with just two fasting measurements — glucose and insulin — making it a simple, accessible way to identify early insulin resistance. Learn more.

• It only requires short clinic visits with repeated testing
