A good article on ageing and health, and what we can do about it. Try to read the whole thing if you can, but here are some of the salient points:
In number terms, according to figures from the Australian Bureau of Statistics, the rate of annual all-cause mortality in the Australian population in 2024 was about 73 people per 100,000 between the ages of 25 and 44. Between 45-64, however, it’s 350 per 100,000. That’s almost a five-fold increase.
Which in turn means we can meaningfully lower our risk of death: we can potentially avoid the sweeping scythe of midlife mortality. In their most basic, layman’s form, the five biggest modifiable risk factors are: to***co use, physical inactivity, poor diet, overweight and obesity, and alcohol use.
Part of the problem is experience. Until our 40s (or even 50s), most of us have never had to worry about making any of these (let’s face it, unbelievably unappealing) lifestyle changes ever before. We’ve eaten badly and drunk too much and lain on the damn couch for 30 years, with no observable ill-effects. Why should things suddenly be different now?
“The ageing process involves a decline in all of the physiological activities of the body. Basically, everything gets worse. You’re in a – hopefully slow – decline, but you are in a decline. There’s no getting around it. Everything from lung function to glucose tolerance – every process that your body performs – slowly but surely gets less efficient, more prone to error, less robust. That’s just what ageing is.”
“Damage has been occurring all along. But it’s often around midlife that it can actually begin to show in diagnosable chronic disease. It’s a question of accumulation. If someone eats really sh*tty food in their 20s and you go and look into their hearts, you can see the beginnings of the formation of plaques: it’s starting to happen. And over time, it just builds and builds, until it gets to a critical point and you either have a heart attack, or you get diagnosed with cardiovascular disease.” Ergo, potential illness and death in midlife.
And so the truth is clear. We cannot live forever; we cannot know when the hammer is going to fall. There is luck and the genetic lottery – neither of which we can control. But there is also a whole variety of things we can do to try to press our finger to the scales of life. The catch is, we must do these things not knowing know how, or if, or when any will be successful.
Welcome to your midlife (health) crisis.
