Would you wear / use this? for mental stress and focus improvement?

looking for real feedback here, trying to iterate on design and value proposition to help with stress and focus in the workplace. using a new type of neurotech sensor that works like a deep pulse oximeter, it gives a specific location reading of blood flow in the brain (kind of like a local fMRI). qs; would you wear the headband form factor? do you need to know when to take a break? would Video based experienced to help calm or stimulate your mind in 5-10mins be more valuable/worth to pay?
