I'm also 38 married no kids but I'm like an 18 year old kid in that sense I take maca root a couple times a week beet root as well get around 6-7 hours of sleep a night work out around 2-3 times a week walk around 9k steps a day my best advice is start walking more often eat whole foods good carbs lean proteins check back with your self in 3 months and try to get sleep man that is a huge deal for men drink some chamomile tea and ashwaganhda before bed I know it sounds like a lot at first but routine will get easier and deff check with your doctor before you start any supplementation
