Thank you for your interest in our study assessing physiological function with age! Your answers to the questions on this screening form will be used to determine whether you qualify for participation in our research study. Your responses are confidential and will only be used for research purposes. DO NOT FILL THIS OUT IF:

-You are taking medications to thin the blood or to prevent seizures.

- You've had a bypass, arterial stenting, defibrillator or pacemaker surgeries.

-You have diabetes or COPD.


Participation in this pre-screening is voluntary. If you agree to participate in this pre-screening, please continue filling out the survey below; if not, simply exit without entering any information. Data from this survey will be kept for future use to contact you about future studies that you may be a good fit for. If you do not want your information saved, please send an email to one of the emails below and your data will be removed.

Feel free to call us at (303) 735-6410 or (303) 492-2485 or email us at or with any questions you may have.

Once you begin the survey, you must answer all the questions and it will take ~10-15 minutes; you cannot save your answers and continue at a later time.

After you complete the form, a member of our research team will review your responses and contact you regarding your participation. If you qualify and are interested in the study, you will be asked to come to the University of Colorado Boulder campus to get more information about the study. For this first visit, you may be asked not to eat or drink for 12 hours before and not to exercise or drink alcohol for 24 hours before.
