A moment ago I was excited to have done a Thursday puzzle so quickly. Then I realized that today is only Wednesday. And I can be fine at Wednesdays, so it turns out that this was no real surprise.

I pulled out 32D Signed, sealed or delivered: PASTTENSE because of how sad the song would have been. I mean could you imagine?
There I was / Signed, sealed, delivered / I was yours back then.
Depressing!
I don’t know how I feel about today’s theme other than that it exists.
16A Prince, e.g.: MALEHEIR
25A Stamp on an envelope [and 16-Across flipped]: AIRMAIL
31A It takes a glider up to launch altitude: TOWPLANE
44A It takes a glider up to launch altitude: PLAINTOE
50A Golf reservation: TEETIME
63A Herbal drink full of antioxidants [and 50-Across flipped]: THYMETEA
Thyme tea? This is the first I’ve ever heard of thyme tea. So I looked it up and came across these questions:

That second one really got my mind going. What does happen to your body when you drink thyme tea?
A little more searching got me to the unassailable medical publication Stylecraze’s 3 Side Effects That Tell You Why Thyme May Not Always Be Good. Those side effects are headaches, asthma, and skin allergies.
It even offered that it could lead to “hypotension: Allergic response to thyme may cause hypotension, as observed in a 45-year old man. Some sources even hint cardiac arrest upon the intake of thyme oil.”
When you talk about a single uncited case and then offer the vague “some sources,” it’s just gotta be true.
I finished this one in 12:19. We’ll see tomorrow what a real Thursday puzzle will do to me.
Happy Thanksgiving, everyone!
