The mental model most adults carry is that choking is something that happens to babies and to elderly people in nursing homes, and that a healthy adult who chews carefully is essentially immune. That framing is only half right.\n",

The rate is strongly age-skewed: adults 65-74 sit near 3.1 per 100,000 and adults 85+ near 26.5 per 100,000 for all suffocation, while adults under 50 sit well under 1 per 100,000. Because the all-ages number is already dominated by the oldest ages most adult readers have yet to reach, the naive compounding is close to correct for a generic US adult. Final figure rounded to 9.1e-4 (≈ 1 in 1,100). Excludes infant choking/suffocation in bedding (coded separately under W75), homicidal strangulation, and intentional self-harm.\n",
