Thanks to everyone who’s reached out with well wishes! I’m feeling fine and getting better. -H

In cell phone video you can see Clinton sway and stumble as aides help her get into her van while leaving 9/11 memorial Sunday.
Her campaign said she had become "overheated," but later revealed she had been diagnosed with pneumonia on Friday.
Clinton was taken to her daughter's home in New York City after the incident and emerged two hours later saying she felt better.
Bakersfield doctors didn't comment on Hillary Clinton's condition specifically, but said pneumonia is a serious illness that people need to pay attention to if they become diagnosed.
"Pneumonia can be more than just a bacterial infection. It can be a viral infection, it can be a fungal infection, but it is an infection of the lungs, so it's a couple of different things that are all kind of tied into one term: pneumonia," said Dr. Kiran Loewen a Family Practice Physician with Adventist Health Physicians Network.
Dr. Loewen said walking pneumonia is probably the most common, "walking pneumonia is kind of a lesser severe form, of pneumonia."
Dr. Loewen said with "walking pneumonia" the patient is less likely to have the high fevers, which allows them to continue being somewhat active.
However, she warned that when someone is diagnosed with pneumonia they are more susceptible to becoming dehydrated. Symptoms of dehydration include feeling more tired than normal, feeling thirsty, or having noticeably drier skin. More severe dehydration can lead to a person feeling light headed, dizzy and eventually passing out.
Those under the age of one year old and over the age of 65 are also prone to their pneumonia progressing quickly. Dr. Loewen said it is important for patients to see a doctor quickly and follow their doctors instructions as well as take any medications that are prescribed.
Dr. Loewen said men and women over the age of 65 are also encouraged to get the pneumonia vaccination. There are two forms of the vaccine that cover different strains of the pneumonia vaccine.
