I responded too fast - I've a microbiology degree and was brought up short by your planning question. I had a six months internship at Scripps Clinic, then an offshoot of Scripps Institute, this in the mid sixties. Then was hired to run an immunology lab.. all by myself, within a med center department at my beck and call. Things progressed and I was happy with where I worked and the people I worked with, but wanted to change fields when I found I was keen on both architecture and landscape, decades later.
I don't regret any of that, I like knowing a bunch in both fields. Sort of a team brain in the works. By my age now, I'm losing track of the old details, but still interested.
