Glass shards even if touched accidently while cleaning up easily penetrate skin and cause cuts and lots of easy bleeding. the injuries from glass are usually superficial or really deep causing permanent damage to internal parts like tendons, etc.?

Unclear question. Even superficial cuts can get infected. Wear protective gloves when cleaning up broken glass. Have a healthy diet, exercise 30 minutes/day, drink plenty of water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs.
