its common to have OCD and absent mindedness....... absent mindedness has nothing to do with intelligence or level of enthusiasm.
What's your point?
Being a perfectionist is also a common OCD trait. Can I now argue with people OCD are less likely to have this problem?
even excluding absent minded OCD types (perhaps you are obsessing over installing a cell backwards?)
accidents will happen but again I posit it is not common.
Furthermore, I will admit the absence of evidence is not evidence of absence but I can't help but NOT notice the rash of threads where people fried their mods.
Seems even less likely considering a good deal of DNA mods have USB charging port, which reduces the need to constantly swap cells.
