What is true about natural handwriting

Natural handwriting changes over time in the same person.

Explanation:

Handwriting is a neuromuscular task. That is it is the function of both muscle and neural coordination. The handwriting changes with age and time. No handwriting samples of same content can be the same although written by the same person as their will be changes in letter formation, spacing and other characteristics due to natural variations.

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
