Summary
On episode 527 of 40+ Fitness, Coach Allan walks through 200 years of history to explain why our lifespan has nearly doubled while our healthspan, how well we actually live during those extra years, has not kept pace.
The causes stack up: less physical work built into daily life, a jump from 22.5 pounds of sugar consumed per person per year in 1800 to over 150 pounds today, industrial farming and synthetic fertilizers that leave animals sicker and produce less nutrient-dense, constant artificial light disrupting sleep, thousands of daily toxin exposures, and a 24-hour news and social media cycle that keeps stress chronically elevated instead of occasional.
His answer is to work the list in order: get the highest quality real food you can afford, make movement a daily priority instead of leaning on convenience, control when you let news and social media in, build a wind-down ritual for sleep, and audit the toxins in your home.

Key Takeaways
- Lifespan has nearly doubled in 200 years, but healthspan hasn’t kept up. Average lifespan grew from 39.4 years in 1860 to 78.9 today, driven mainly by infant survival, safer conditions, medicine, and food security, but obesity and lifestyle disease rates have climbed right alongside it.
- Sugar consumption jumped from 22.5 pounds a year in 1800 to over 150 pounds today. Processed food and cereal companies built entire industries around taste and shelf life rather than nutrition, engineering products designed to make people eat more of them.
- Industrial farming produces sicker animals and less nutrient-dense plants. Crowded animal operations require routine antibiotics and growth hormones, while produce is bred for durability, picked early, and artificially ripened, so it spends less time in the ground absorbing nutrients.
- Synthetic fertilizer and glyphosate changed what ends up in our food. Chemical fertilizers, widely adopted since 1861, and glyphosate (Roundup), introduced in the 1970s, both show up in the food supply, with glyphosate specifically linked to cancer risk.
- Artificial light disrupts sleep in ways our bodies haven’t adapted to. Household electric light is barely 100 years old (as late as 1925, almost half of U.S. homes had no electricity), leaving little evolutionary time to adjust to constant nighttime light exposure.
- Tens of thousands of daily chemical exposures, over 800 of them endocrine disruptors, add up. Furniture flame retardants, yard pesticides, and pharmaceuticals in the water supply all contribute to a toxic load that interferes with hormones like estrogen and testosterone.
- 24-hour news and tribalism turned stress into a constant state rather than an occasional event. Unlike the short burst of stress from seeing a physical threat, chronic negative stress from nonstop news and social media keeps cortisol elevated and steadily undermines health.
- The fix works best in order: food, movement, stress, sleep, then toxins. Get the highest quality real food you can afford, prioritize movement over convenience, control your news and social media inputs, build a nightly wind-down ritual, and audit household toxins using a tool like the Environmental Working Group’s app.
