Re: I predict excitement
In my younger days I had a pysics prof tell me that a "proper" lab scientist needs an electric shock every so often, one kV making you feel "quite lively".
Nowadays i mostly turn off the power when working on circuits though I have done it without, being careful, and knowing that the off 240V zap does little harm.
When working as an electrician (in even younger days) in a working factory, sometimes it was considered unavoidable to wire something up while live, with well-insulated tools, shoes, and an abundance of caution.
