An engineer and an anti-vaxxer were walking through the woods when they came upon a bridge across a crocodile infested river.
The anti-vaxxer asked the engineer “What are the odds of us making it across that bridge safely?” The engineer took out his calculator and his tape measure, did a structural analysis and said “99.97% chance we’ll make it across that bridge safely.
The anti-vaxxer responded, without even thinking “Forget that, I’m swimming!”
