In one sentence, describe what the following article is about: Some areas of the world are naturally easier to get exposure to sunlight (those areas that are geographically near the equator), as opposed to northern latitudes.  The optimum time to get sun exposure to produce vitamin D is between 10am – 3pm, as these tend to be the hours of peak sunlight. Five to thirty minutes of sun exposure a couple of times per week should be sufficient to meet most people's vitamin D requirements. Note that people with naturally darker skin require more sunlight to synthesize the same amount of vitamin D in the skin. This is because people with darker skin have more UV protection from the increased amount of melatonin in their skin. Also, people of older age need more sunlight to synthesize vitamin D, as the skin's ability to make vitamin D from sunlight decreases with age. Note that you are not absorbing vitamin D from the sun; rather, sunlight is what causes your body to produce vitamin D. Although we are culturally and socially trained to wear long clothing and sunscreen to protect ourselves from the sun's rays, if you are wanting to produce vitamin D (and particularly if you live in a northern climate or it is a less sunny time of the year, such as the winter), you will want to expose more skin in order to maximize your vitamin D production. While sunlight is one of the best ways to increase your vitamin D, once you have gotten your dose of sunlight, you must continue to exercise caution in the sun, even if it is cloudy or overcast. This means wearing sunscreen and covering your skin. The sun's rays, in addition to being a source of vitamin D, can be cancer-causing if you have too much exposure, particularly at times of the day with peak sunlight.  Experts suggest that five to 30 minutes of sun exposure, without sunscreen at least twice a week should provide adequate vitamin D exposure. As long as your face, arms, legs, and/or back are exposed, you will be able to reap the positive benefit of the sun's rays. Vitamin D is fat-soluble, so it is stored in the liver and fat, You don't have to get sun exposure every day to have enough Vitamin D Do not use tanning beds as a source of vitamin D. Although they do indeed provide vitamin D, physicians say that the risks outweigh the benefits. It is better to opt for a combination of natural sunlight or a supplement instead.
Summary: Make an effort to get sun exposure, particularly if you live in certain climates. Expose your skin if you are wanting to maximize vitamin D production. Ensure that you are getting sun exposure in a safe way.

Problem: Article: By growing herbs such as mint, dill, or clover, you’ll attract ladybugs and lacewings. Both of these insects are known for eating aphids, which will help decrease the number you have eating your plants. You can also purchase ladybugs or lacewings from a farming supplier to release in your yard, if desired. Wrens, titmice, and chickadees are all helpful when it comes to eating aphids. To encourage these birds to live near your yard, plant shrubs with dense foliage or small trees perfect for nesting. You can also set up a bird feeder to help attract the birds. Install small birdhouses for the birds to live in as an alternative to planting shrubs or trees. These yellow traps catch aphids using their sticky surface—just hang them on a branch or position them next to your plants. You can buy sticky traps from a home and garden store, as well as online. Grow plants that attract aphids, like asters or cosmos, planting them away from the plants you want to protect. The aphids will be drawn to these plants and will stay away from less appetizing plants as a result.  Aphids also like dahlias, larkspur, and zinnias. These decoy plants are a bit like a sacrifice to the aphids in your garden. The aphids will concentrate on them, so avoid becoming too attached. Not controlling aphids will only lead to an increase in their numbers, eventually leading to their spread to other plants. You will still need to police their numbers on your decoy plants. How far away you plant the trap plants will depend on the specific type of plant and how much room it needs to grow. Start with at least a distance of 2 feet (24 in).
Summary:
Attract beneficial insects that will eat the aphids. Draw in bug-eating birds to help fix the problem. Buy a sticky trap to catch the aphids. Use plants that aphids love to lure them away from other plants.
