We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
Good technique is essential. Do them wrong (eg lifting with your back istead of your legs) and you can hurt yourself. Do them right - it's not complicated - and your whole body gets stronger including your back. Deadlifts prevent aging! Mrs. BD does them weekly, and swears at by them.
Besides general fitness, just doing 5 sets (including a warm-up set) of heavy deads once-weekly has been great for my posture. Generally finishing with my 6-8-rep max. I only aim for a max one-rep effort every couple of months, just for fun (?). Since I am not a big strong guy, I can probably only get to around 300 with a trap bar at this point, and that is good enough for government work. With a plain bar, my grip tends to fail first. (I do need to work on my grip strength.)
Mens sana in corpore sano. (The former is a tougher challenge than the latter.)
(An important deadlift tip - and for barbell squats too - that is rarely mentioned: Make sure your bowels are well-emptied first. The intra-abdominal pressure gets high with heavy weights, and you do not want an accident. Farts are expected, but...)
Do you do your deads with a regular bar or trap bar?
Sumo or conventional?
RDLs (Romanian deadlift)?
Snatch grip leads (from rack)?
Have you ever tried one leg "straight" leg deads (link: https://www.youtube.com/watch?v=7uA1PLNIWK8)
I tend to rotate the different variations every month.
RE: Flatulence; Mr. Rippetoe notes that "sometimes farts have a solid core." and recommends the same as you.
Also from personal experience with deadlifts I would recommend that one double check one's math when adding weight.
My previous outing I had done a good work set at 280. So I put 285 on the bar and picked it up. It felt REALLY heavy, so I looked down and redid the math. I had stepped from 280 to 295.
Which is only 5 pounds from 300.
So yeah, that's what I did. Because 300.
And got both golfers AND tennis elbow at the same time. TO be fair I'd been playing hurt anyway, but that put it over the top.
Once you pass...10 or 12 the tendons don't heal as fast as they used to.

Felt a pop and immediate pain at inner left elbow on last rep of a set of five at 375. Been out of the gym a month now with grade one (I think) elbow sprain that left me unable to lift much weight (like the cat) without pain in that arm. I'm 66, and tendons don't heal very fast at any age.
