## How that compares

*Defibrillator against things of a similar time.*

- Cheetah: 8–17 yr
- Dishwasher: 7–13 yr
- Sofa: 7–20 yr
- Green anaconda: 10–30 yr
- Defibrillator: 7–12 yr
- Microwave oven: 6–11 yr
- Lawn mower: 6–15 yr
- Capybara: 6–12 yr

## What that means over time

*Assuming the typical lifespan above and immediate replacement.*

| Period | How many you would buy |
| --- | --- |
| Per year | 0.111 replacements |
| Over 10 years | 1.1 of them |
| Over a 30-year mortgage | 3.3 of them |

> Lifespans are medians under ordinary use, not guarantees. Maintenance, how hard it is used, and build quality move individual examples a long way in both directions — which is why the range above is as wide as it is.
