Article: Nettles are covered with tiny hollow hairs, filled with irritating chemicals. When you brush against these hairs, the tip breaks off and releases these chemicals, causing the sting. To harvest nettles with bare hands, you'll need to learn to touch the plant without breaking the hairs. Nettle plants vary greatly. Some have almost no hairs, while others are covered in them. There is one useful pattern you can use, however: plants in full shade tend to have many fewer hairs than plants grown in the sun. Typically, a nettle has stinging hairs mostly on the underside of the leaf, and little to none on the top surface. These should all lie along the leaf pointing from the central cleft to the outer edges.  Don't assume your plant will match this description. Nettle plants have a high degree of variation, and the name "stinging nettle" actually describes at least two species. Look for the hairs with your own eyes. The stem also has hairs. These angle down or up the stem on some plants, but poke out perpendicular to the stem on others. If your plant looks like the last type, it's best to avoid the stem completely. It's easy to get stung by another leaf when you're focused on the one you're grabbing. Stay near the top of the plant, where the leaves are smaller and less likely to brush against your hand from above. Nettles often grow in dense patches, so keep an eye out for nearby plants swaying toward you. You're less likely to break the hairs if you grasp from the base of the hairs, rather than run your hand into the tips. If the stem looks safe to grab (with angled hairs), aim for a spot just below the leaf. This will make it easier to pluck the leaf off the plant. A quick, firm grasp is your best bet to avoid breaking the hairs. If you're too gentle, you'll almost always snag a hair and break it. Once pinched, you can twist the leaf and pluck it off the plant. There's no guarantee you won't get stung even with this method. Try this at your own risk.
Question: What is a summary of what this article is about?
Understand how nettles sting. Choose a plant in the shade. Look closely for the hairs. Choose a leaf near the top of the plant. Approach the leaf from the direction the hairs are growing. Pinch the leaf firmly.
Article: One of the most important parts of maintaining your travertine floor is the removal of dust and debris on a regular basis. Try using a microfiber dust mop on your travertine floors several times a week. You should wet mop your floors weekly, or more often if the travertine floor is in a high traffic area. Regular mopping with a travertine-friendly cleaning solution will help your floors maintain their natural beauty for years. You can extend the life of travertine floors and avoid unsightly stains by cleaning up spills as soon as they happen. This is especially important if you spill something acidic like tomato sauce, carbonated beverages, or wine. The acid in these products can damage travertine. Travertine floors can scratch easily. Protect high traffic areas by placing area rugs, doormats, and runners on the floor. This will help prevent dirt and debris from scratching the surface of the floor. It is important that you seal travertine floors on a regular basis. Sealing floors helps prevent damage to the surface of the travertine. Contact the manufacturer and/or installer of your travertine floors to find a sealant that will work for you.

Dust mop regularly. Wet mop floors once a week. Clean up spills immediately. Place rugs in high traffic areas. Seal travertine floors yearly.
