The lung of a smoker and a healthy lung

Fully inflated lungs are huge.

You reckon it's real?

Yes, very much so. To strengthen my opinion, I will also point out that 1. the woman is behind and not beside the lungs in the picture, so it's a matter of perspective, and 2. it is possible that these lungs comes from 2 big men, and that the woman is quite small.
There should have been a banana for scale.

There should always be a banana for scale. I thought about the perspective thing but she'd only be 50cm back, not enough to account for the size difference. But eh, I know nothing about lungs and you're probably right

Nah, you just threw out your money.. If you want to see some dead bodies again, come to my place, I'll show you for free.
