Absolutely no disrespect due to your younger age; it's just a different time. When I began working on cars (1970-ish) I already had a head full of knowledge from reading every car magazine I could get my hands on. I knew how stuff worked, but it wasn't just me - my entire generation had at least elementary mechanical knowledge even if they were not necessarily "mechanically inclined" like I was/am. Sadly that is not deemed important any more; and as a result many younger people have not developed what I consider essential life skills - fixing stuff.
