The last thing: The last thing would be to fix our dryer the other day. And just prior to that, to work on a customer's electrical panel, adding a few new circuits. And just prior to that, to build a couple new computers. And on and on.
There is NO comparison with a handheld when working with your hands while you need the light. Unless you are completely idle, and don't do ANY physical work, it seems most logical to me, that everyone would have a need for a headlight, even if they are not real active outdoors (camping, etc.).
Once you get one and use it, you will likely want to keep upgrading. I started out, years ago, with just a cheap one from Walmart. Then, after a few more of these cheap bulky models, went to a Petzl Tikka, then a Princeton Tec Aurora, then a Nuwai, and then a Streamlight Argo. Then, just a few weeks back, I bought a Zebralight H501 and now I think I have the ultimate headlight for working with my hands.
