My sister asked me if I thought she was too old to go back to school to earn a degree. She's only 51. Heck no, go and do not stop. My neighbor is almost 80 and just got her first long arm. She did most of her quilting by hand and some by DSM. She giggles every time she learns something new about her machine, a nervous giggle but it's fun to watch her. She'll call me and say "Theresa, do you have a minute? Sure I've got a couple hundred!"
