I remember doing tedious joined up handwriting lessons at school, but I don't think they had any more than subconscious impact on my style of writing outside those lessons

My writing has the pen leaving the paper only at the end of each word, with "t"s crossed and "i"s dotted then, so the descenders of {j,y,g} loop round into the next letter.

Most of my letters with a vertical line (l, b, d, t, but not h) have the vertical line formed by a narrow loop, but only if they occur in the middle of a word.
