If the scout can demonstrate the he can use a tool safely and correctly then he should be allowed to use it. I grew up using a welder when I was 12 and all sorts of saws and drills and even cutting torches by age 10.
Eat foods rich in Vitamin B-6: Foods with vitamin B-6 have a number of benefits after you give blood. Your body needs the vitamin to build healthy blood cells and it helps the body break down proteins. Because proteins contain many of the nutrients you need after giving blood, eating vitamin B-6 foods can be helpful.
The men repeated the 3K time trial 3, 7, 14 and 28 days after donating. The researchers also measured the men's hemoglobin concentration on those occasions. Hemoglobin is a protein in red blood cells that carries oxygen from the lungs to the rest of the body. Three days after giving blood, the men were, on average, 5.4% slower than before giving blood. Performance remained compromised a week later, although not by as much. By the time trial 14 days after giving blood, the men ran as fast as they had pre-donation, even though hemoglobin levels remained 5.9 percent lower.
