Jimmy Carter is a founder for Habitat for Humanity?  LOL  You need to get away from fake news https://www.habitat.org/about/history  

The way to prevent dehydration  is well known - you think someone is a hero for getting so dehydrated they end up in the hospital?  Further, you think Trump should be working for HFH while he's trying to run the country? Even your hero Jimmy Carter didn't manage to do that. He's RETIRED, with an enormous pension, hence the time to spend on charity endeavors.   

Do you also imagine that Carter cooks his own meals, does his own laundry, cleans his house, maintains the landscape, manages finances and investments, and prepares his own tax returns?   

Next time you want to deride Trump, you might want to come up with something that has more logic.
