You reminded me of a conversation I had this morning about goats eating whatever... no offense since you do not come off as goatish.
I live on energy drinks, coffee, nootropic supplements, and one meal a day that someone else usually makes for me. I forget to eat all the time and have to be reminded. I took gymnastics and Kung Fu in my childhood and teens. I danced for years so my body may be used to it's current form. I am not extremely worried about it regardless. I am a bit of a hygiene freak though since I have an aversion to germs but have chilled, so brushing 5 times a day and washing my hands excessively is a thing of the past. It was OCD anyway... Shopping makes me extremely happy sometimes and I can get carried away. I spent over $100 on incense last month and just bought more yesterday. grrr
Sometimes I spend more than I keep available for random stuff in my self imposed allowance but I am not materialistic since I give a lot of it away sometimes before I even use it. It is more the thrill of the hunt for me. Except for electronics. I am very possessive of my technology. I have 3 working tablets and as much as I want to give a couple of them away I can't. They contain particles of my energy and I don't want to wipe them first. I have a strong competitive streak too which seems to be linked to my 4ish traits in enneagram.
Only reason I thought IEI (not EII) is some of the things you mentioned liking and some of your personality traits could apply to IEI. I guess the propensity for Te will be revealed in time. If you are ILI. Anyway, it is nice to have you here. I will probably like reading your posts.
Edit: I read you edit. Got it...
