If you work with your hands and back, avoiding heavy lifting is completely understandable.
For many of us, however, we work with time or with trust.
If someone asks you to approve their new project, “It’ll only take a minute,” they’re offering to save you time, but at the risk of the trust you’ve built. It’s not a light lift, it’s a huge risk.
If someone says, “please forward this to everyone in your address book, here’s a simple script to do this automatically”, that’s a heavyweight indeed.
Just because it’s fast doesn’t mean it’s worth it.
