Been studying plant-fungal interactions for about 10 years, including a master's degree I dropped out of and never actually finished* so I'm full of fungus facts i don't really get to use ever.
*Actually did all the course work and lab work but didn't finish my thesis in time
Because at my school I had to fill out a form saying "I am starting my thesis on this date, on this topic, with these advisors" and part of the degree program terms is you only have X amount of time to finish once you officially start it. I can technically start over on a new topic, but I have to get some advisors to sign off on it and everything again and I've moved so it's a big hassle.
