Sex hormone-binding globulin

My latest InsideTracker bloodtest shows very high SHGB, too high. I've looked around for a solution, but there seems to be very little research. You mentioned it briefly in one of your interviews, but would you care to do a deep dive?

Waking up at 5am every morning, trying to fall back asleep

I often wake up before I would normally (complete darkness in bedroom) and still feel tired. I try to fall back asleep but it often takes 1-2 hours. I feel the cortisol getting released. Is it fine to try to fall back asleep or is it better to just wake up at 5am?

Is it possible to improve reaction time at 30+?

Does reaction time go down with age? Can it be improved with training? Can people maintain good reaction time at old age? I'm talking about physical reaction time, like hockey goalie

Alcohol / Is there any science for DHM?

I quit drinking permanently as a result of your alcohol podcast. Thank you for the information and for helping me make an evidence-based decision. I am still curious about Dihydromyricetin (DHM). When I would take Cheers health it seemed to actually work, although my sleep still was terrible. Is there any science showing mechanism or efficacy? I have no relationship with the product but my wife still drinks and I'm wondering if it's still worth buying.
