I’ve been working as a certified care worker for 17 years. I’m Nanaka, a caregiving web writer. I decided to pursue this profession because I wanted a job that would help people. Having worked in day care for many years, I’ve experienced a wide variety of recreational activities. Exercise set to music, in particular, always created a cheerful atmosphere and was very well received. I’d be delighted to continue delivering writing that resonates with readers through caregiving-related articles. Thank you for your support.

What is the reason ginkgo trees are often planted as street trees?

In many towns, roadside trees are planted, adding color to the scenery.

By considering their thick leaves, we can infer the tree’s characteristics.

The answer is that ginkgo trees are highly resilient and hard to burn.

They grow robustly even in urban environments and, in emergencies, provide safety benefits, which is why they are favored as street trees.

What symptoms are likely to appear simultaneously when one becomes malnourished?

Eating is essential for living, and being mindful of nutrition leads to health and happiness.

Ideally, it’s best to have knowledge rather than experience, but some people may recall it from personal experience, such as having an unbalanced diet.

For maintaining good health, how many grams or more of vegetables is it desirable to consume per day?

Although vegetables are strongly associated with being healthy, it can be hard to know how much you should actually eat if you’re just going about your day.

Let’s find out how much vegetable intake is recommended per day and use that to plan healthier daily meals.

First, think about how many vegetables you’re eating in your regular meals, then check the required amount.

By comparing whether you’re eating too much or too little, you’ll get a concrete picture of what you need—highly recommended.

The answer is “350 grams per day,” but that doesn’t mean anything goes as long as you hit that number.

In addition to how you reach that amount, be mindful of nutritional balance as well.

Are worker bees male or female?

Bees that fly around outside and collect nectar to bring back to the hive give us the impression that they contribute to the colony.

So, which sex are these commonly seen worker bees—male or female? Considering that there is a queen inside the hive and that worker bees do not have reproductive capability, you might be able to guess.

The answer is that, like the queen, worker bees are female.

Males are born only during the breeding season, so most of the bees you see are likely females.
