I’ve aged out of jury duty in the state where I live, but when I was eligible the notice I got said this is the courthouse you’re assigned to, but you could request a different location.
In the U.S. most states do not exempt/prohibit lawyers from serving on juries.
As a practical matter it appears that they typically are excused when called.
When I was in one venire we were all waiting in the audience chairs for jury selection to begin; the attorneys and the criminal defendant were in place; then the lawyers went up to sidebar to confer with the judge for a while. When they broke, the judge sent us all back to the jury pool room and after a little while came back to inform us that the defendant had taken a plea deal, with a joke about how we must have “looked like a hanging jury.”

Lawyers can and do serve on juries in Massachusetts.
Typically is a but ambitious in this context. I’d say often but not even near “always”. I know of of many trials where attorneys have served.
Looks like your experience is atypical. 
I think that depends a lot on what “excused” means , exactly. There have been times and places where certain situations will more or less automatically exempt you from jury duty - sometimes it’s your occupation or your age. There aren’t any of those in my state anymore - there used to be a whole list of occupations that were exempt. It changed about 30 years ago and now it’s all done on an individual basis - rather than exempting all doctors or lawyers or clergy members.
But that doesn’t mean those people actually get on a jury - I’ve never served on a petit jury even though I’ve been called a number of times. Not civil, not criminal. Lawyers apparently don’t want me on their jury because of the jobs I’ve had - and I would imagine lawyers tend not to want other lawyers on their jury.
Grand juries are another story - presumably because defense attorneys have no say.
Sometimes we do want lawyers on our juries. And sometimes we have to use our limited challenges on others who are worse and we get stuck with a lawyer. In may cases I’d prefer a judge trial to a jury. (Around here is is the civil defense bar that typically files a jury demand )
I was called like clockwork, despite working for the courts and knowing virtually every player in both civil and criminal courtrooms. I was never released solely on the basis of my position with the courts. I was frequently released because one or more attorneys on the case worried I was biased for the opposing side – which I took as a bit of a compliment, since both sides shared the same fears.
I was sworn in as a regular juror one time because (I later learned) both attorneys believed I would be favorable to their case. Alas, we didn’t reach deliberation. The defendant took a plea offer on the second day of trial and we jurors were excused.
I saw many attorneys serve on our juries and even one judge. We did a lot of jury trials because of the largest state mental hospital for men in the State of California, as well as a very large medium security prison facility, being located in our county. The mentally ill folks are entitled to regular and frequent reviews of their mental health status. Some of those reviews are heard by juries. Just about everyone in the county was called as often as they became eligible.
It worked in one of the trials I did. I’ve shared the story a couple of times on the Board before and won’t repeat it again, but suffice it to say, crapping your drawers in the middle of voir dire is pretty much a sure fire way to get excused from jury service.
It’s the same for me (another Canadian lawyer). In fact, nowhere in Canada are lawyers eligible to be jurors. It’s just the way things are here.
I do remember that at one point, we were asked to raise our hands if we were not American citizens (nobody did) and also if we were not residents of the county (nobody did that, either).
I remember an old “Family Circus” cartoon where the kids are in a voting booth with Mommy, and it’s captioned, “Mommy, that’s not the lever Daddy pushed.” Until just a few years ago, I thought, “Yeah, so?” Now, I get it.
What’s the maximum age? Now that I think about it, I don’t think I saw anyone yesterday over the age of about 75, but maybe that was just the group that was chosen.
Several months before he died in 2023 at the age of 90, my dad got a summons, and he did go to the courthouse. He said he took a magazine with him, and had a bottle of Boost in his pocket, and was excused at lunchtime.
In Massachusetts, as of age 70 you can request to no longer be summonsed for jury duty.
In three of the four states I’ve lived in as a citizen it’s been 70 years old and you can ask to be excused or taken off the list. In Virginia it was (and is) 73.
In all four you can serve if you want to. It’s just that being 70+ or 73+ is an automatic out if you want it.
My “best” excuse, one I like to tell.
Guy is on the jury pool, and asks to be released. “I work for the railroad*, your honor.”
Judge says, “I’m sure the railroad can get along without you for a few days.”
“Oh your honor, I know they can. I just don’t want them to find out!”
*it’s an old joke
In fact, one of the arguments against women’s suffrage was that it would just give married men two votes. And in the recent election some signs were posted in Ladies’ rooms all over the US, pointing out that women didn’t have to vote the way their husbands ordered.
Had he been working on the railroad all the live-long day?
Turns out that Suni Williams and Butch Wilmore have both been summoned for jury duty but cannot attend for some made up preposterous reason. they are the astronauts that are NOT STRANDED on the space station
I think he hasn’t been working, he just passes the time away.
There’s a judge in an adjacent county to mine that would issue arrest warrants if they didn’t show up for voir dire.
