Before you commit
Aquarium Keeping
- Losing a few fish to a tank that cycled too fast would gut you.
- You want results now, not weeks of patiently waiting out the nitrogen cycle.
- Weekly water testing and partial changes sound like a chore you'd skip.
Metal Detecting
- Digging eleven pull tabs and a rusty bolt for one coin would deflate you.
- A sore back from knees-in-the-mud digging would put you off fast.
- You want a reliable payoff, not mostly foil and corroded nails.
