I learned quickly with a red dot is that you can't focus on the dot to put it on the target. Look at the target and let the dot come to the bull. They're weird. Didn't use it much after. Prefer irons.

Someone who's been to trade school then entered a trade and learned the ropes from the more experienced is just as "educated" as Someone who's gone to college. Probably more.

Yep, Ruger 10/22 Carbine (basic model, nothing fancy), 22 Long Rifle, with a red dot and co-witnessing iron sights. Shooting from about 20 yards, a mix of red dot and irons, but it was only the second time my Grandson has been shooting. He shot about 2/3rds of the rounds.

If he can shoot iron sights he will do fine. Anything past that is iceing on the cake. Kudos to you.

He prefers to irons over the red dot. His eyes are young.

Creatine supplementation and muscle-brain axis: a new possible mechanism?

The brain and skeletal muscle have a high energy demand, of which creatine is an important regulator. Creatine acts as both a spatial and temporal energy buffer and reduces oxidative stress and inflammation. Creatine supplementation is well-recognized to enhance exercise performance, muscular strength and lean tissue mass, with emerging research showing benefits on cognitive function. Herein, we discuss the potential muscle-brain axis and the purported benefits of creatine supplementation on myokines, with a focus on brain-derived neurotrophic factor (BDNF). Myokines and the muscle-brain axis have been implicated in strength, endurance, neuroprotection, and cognitive performance, particularly in aging and clinical conditions. Creatine is a pleiotropic molecule and the mechanisms are multifactorial, however, they appear to be associated with improved bioenergetics, muscle hypertrophy, anti-inflammatory effects and on improved glucose metabolism. Despite the growing body of research on creatine, limitations such as variability in study designs, dosages, and individual responses need to be carefully interpreted. Further research is warranted to verify this hypothesis and to establish optimal supplementation protocols, particularly, in terms of its short-term and long-term implications for neuromuscular and cognitive performance.

Had the grandsons helping me with an oil change and tire rotation on my truck. Fun times. The older one will help and do what he is asked or told to do, but not enthusiastically. The younger one wants to be under the truck getting dirty, and can't keep his hands off of anything related to what we are doing. And he never stops talking, LOL.
