It's a case of perceived risk v actual risk - you can't actually hurt yourself on a zip-line unless your legs fall off. So how do you tell the difference between "soft adventure" and an activity where there is genuinely an element of risk - like canyoning or whitewater rafting - because your experience isn't under someone else's control?
Easy, says my husband, a committed 10,000-hours man in several areas, including paragliding, outdoor rock-climbing and insanely arduous tramping trips into places even possums won't go.
There are "sack of spuds" adventures and then there are "real adventures", he says.
A "sack of spuds" adventure is one that a loose arrangement of potatoes would survive unmashed. In other words, any wimp could do this and be rocking the T-shirt on Facebook by teatime.
An accreditation agency - Sosafe (Sack Of Spuds Adventure For Everyone - could be charged with licensing operations. If your business gets the Sosafe stamp, you're good to go after just about every sector of the tourist market.
Of course there's a place for family-friendly activities; not everyone wants to suffer for their fun. However, whatever the activity, the goods - both human and mechanical - should be fit for purpose.
We have a right to expect that crews will be ready and able to do their jobs, not gung-ho cowboys who got on the weed the night before.
But there's a huge difference between a shonky operation and an activity that carries an element of risk because the actual, unvarnished outdoors and some decision-making are involved.
We shouldn't have to make adventure unadventurous.
If you don't want to risk breaking a nail, only vacate the cafe if you can see the Sosafe logo.
Leave the less predictable stuff to the people who don't mind getting dirty and covered in bruises.
One person's hell is another person's good time.
