The brain is made of water and cholesterol.

The brain contains 23 percent of all cholesterol in the body. And the brain is approximately 75 percent water.

A lack of either of these two things is dangerous — and the relationship between the two is related to overall brain health. 
But you need to know that brain efficiency, memory function and attention span are all related to how much water and cholesterol your brain has at any given moment.
Field Day requires all those functions during the event and on your way back home.

As you age — and I am not talking about being 80 years old, but after your 20s — you need to drink more water to compensate for changes in your body temperature regulation.

Still, even though almost everyone is dehydrated, most seniors are very dehydrated indeed. That's because our thirst mechanism begins to fade with age. Even people who are seriously dehydrated will not drink water placed in front of them. 

Avoid dehydration- Drink plenty of water during Field Day.
Please, Remind fellow attendees to HYDRATE. We have lots of water, if we need more, we'll get it.

Be safe for Field Day
