Be aware that humans are falible:
Monday Mornigs and Friday afternoons may cause lapses in concentration.
Lapses in concentration can cause death. Serious.
If I've done 8 pages of A4 maths my brain lags at the end of a shift... you're still thinking about the last nanometre (1E-9) measurement as you press the big green button, an 8 can seem like a G or a 6, a 1 can masquerade as an I or a 7 resulting in a rapid traverse at full velocity in the undesired direction.
Always have your hand over the E-Stop. Always.
