This study lasts about six months. During the study, participants will give blood samples and have simple energy measurements each month. They will also fill out surveys every month about how they are feeling. In months four and five, participants will take part in a short stress activity. This may include several days of heat exposure, slightly less sleep than usual, or exercise.

We are doing this study to learn more about how environmental contaminants (e.g., "forever chemicals") can affect people's likelihood of developing liver disease.

The goal of this study is to learn more about how certain hormones and cells in the pancreas help keep blood sugar at a healthy level. This is very important when the body does not respond well to insulin, which can happen with obesity and diabetes. By doing this study, researchers hope to find better ways to care for and treat diabetes.

We are doing this study to determine the impact of smoking electronic cigarettes (e-cigs) on lung health. This will be done by comparing study procedures and imaging results between healthy participants that use e-cigs versus those who don't.

If you are in this study, you will fill out an online survey that takes about 30 to 40 minutes. The study team will also collect basic information about you, such as your age and background, along with results from your colonoscopy. This information will be saved in secure research databases. You can choose to give extra samples if you want. These may include a small blood sample taken before your colonoscopy, a stool sample you collect at home using a kit, and extra tissue from your medical procedure. The study team will also review your health records over time to see how you are doing.
