This. I’m an old dad. I realized two years ago that to keep up with my pre-teens I had to change my lifestyle. For me that meant cutting out alcohol, not eating processed foods, avoiding sugar, reduced caffeine, way more protein and doing calisthenics. I sleep well and I have energy. I just have to keep this up for 10 more years when my youngest will be 21, then I can die. ;-)

Haha! Very interesting life goal - When your dependents have sucked all the life out of you, you can kick the bucket:) (And am sure it’s worth it)
