use butt connectors, ring terminals, and spade clips ad a good crimper. Before crimping, I’ll coat the wire end and the connector with a dielectric paste, avoiding silicon sealer, as it can shrink and allow moisture in. A layer of heat-shrink tubing guarantees a water tight worry free connection.

There is a long-standing convention in Usenet news
which also commonly appears in Internet mail of
using “– ” as the separator line between the body
and the signature of a message.

R Markdown
R Markdown is an authoring format that enables easy creation of dynamic documents, presentations, and reports from R. It combines the core syntax of markdown (an easy-to-write plain text format) with embedded R code chunks that are run so their output can be included in the final document. R Markdown documents are fully reproducible (they can be automatically regenerated whenever underlying R code or data changes).

Insufficient sleep results in cognitive fatigue.
Insufficient hydration and sustenance results in physcial fatigue.
Insufficient physical strength and cardiovascular investment/exercise results in both.
