Before you commit

Mountain Biking

A twitchy bike on a trail faster than you would rattle your nerves.
The unglamorous, honest grind up the climb is effort you would rather skip.
Crashes, roots, and rock gardens sound like injury risk, not fun to you.

Scuba Diving

Expensive gear plus certifications and required dive buddies put you off.
Fiddly pre-dive equipment checks every single time sound tedious.
Not being able to surface freely would make you feel trapped.
