Testosterone and weight lifting
Can you discuss how weight lifting can increase testosterone. Can you additionally discuss how working out different muscles groups affects testosterone? For example, I feel (although I do not have blood work to confirm this) that my testosterone increases most after working out my leg muscles.
Eye tracking applications
There are eye tracking glasses today capable of taking precise (and sometimes also accurate with calibration) measurements of a wearer's pupil diameter, gaze direction, and blink rate. What do you envision as the best early applications to leverage these devices for either general health (think: ubiquitous fitness trackers but for cognitive load) or for particular applications (eg monitoring a particular disease)?
Should I remove braces or not?
I hope this message finds you in good health and spirits. I am writing to express my admiration for the valuable information you provide in your videos. Your insights have been truly enlightening and I have learned so much from watching them. I recently got braces in August 2022 and I am now faced with a decision about whether I should continue wearing them for another year or remove them. I recall that you mentioned in one of your videos that braces can have a negative impact on health and I would be honored to receive your professional opinion on this matter. Your expertise and guidance would be greatly appreciated. Thank you for your time and the wonderful work you do.
