I am working out to be a better volleyball player. But do I need to worry about my diet? I mean I will try to eat good foods but do I really have to be strict about it? And any tips of what I should eat?​

Answers

Answer:

Trying to improve yourself is great! It really depends on your age, but you should always have a healthy, balanced diet. You should eat nutritious foods like fruits and veggies, and also build on protein like chicken or fish. You can eat junk food once in a while like chips, or you can switch to whole grain snacks instead like sun chips instead. I hope this helps you become a better volleyball player.

veggies and fruits are obviously incredibly good for your body when working out, same with drinking tons of water! it is good to have a balanced diet so definitely don’t restrict eating carbs but find healthier ways to incorporate them into your meals ;)

1. Obviously, if the water fountain pump stopped working , it wouldn't shoot water into the air. (i didn't really know what to put here sorry)

2.Veins and blood vessels are the body's pumps that dispense blood through you and I every second of the day.

3.It is similar because if the pumps in our bodies stopped working, blood could not get transferred to the heart. The same with the fountain (it would not work). Both the fountain and a human body will shut down if the pumps do not work.

Hope these help you, have a fantastic day !

What age is it appropriate to feel sexuality interests?

Answers

Answer:

In my opinion, it doesn't matter.

Its okay to experience how your body feels.

This might not be the perfect answer your looking for, but I hope this helps.

There is never a right age to feel these kinds of things, there is no correct answer.

But, I need to say this, be careful; you want to choose the right person. This doesn't necessarily mean that you'll want to be with them forever, but it's important that something bad doesn't happen. Make sure that you know them well and that you both consent to this.

I will say, if you're still considered a child, then make sure it's someone around your age. I'm talking about 15 to 17 years old, not small 7-year-old children.
