I partially agree - pushing limits is plain stupid given enough time, every single time injuries happen, to everybody out there. If they say not to them they are either lying or just begun the sport recently.
I have different approach, with similar result so far to those bodybuilders without actually doing it - don't lift your max, but do it with free weights as much as possible, in good form (the most important bit long term). You don't need to look ridiculously bulked, say well-defined is more than enough, even for women's attractivity. Those massive muscles always hide very unhealthy eating habits (ie > 200g of protein every day will mess up your organs and joints badly over decades) and tons of injuries, plus they are very hard to maintain if you actually want to be happy in your life and do other stuff.
I strongly recommend removing some weights and adding repetitions, you can still reach failure threshold if you want, but in much safer way. Easier to maintain perfect form for each exercise too. You mention lifting heavy stuff in weird positions - that's recipe for injury regardless of age or shape, rather just be a bit smarter with lifting.
What is much better to be able to have some stamina - weightlifting on the limits alone ain't going to give you much of that (saw more than once a ripped guy who didn't do any cardio trying to make >1000m altitude difference hike, well he struggled a lot, on a way up and then knee pain started say in the middle of descent).
There are tons of things apart from main, most visible muscle groups that you really want to train - small stabilizing muscles, tendons, ligaments, joint flexibility, and stamina for all of those. Body is a complex and interconnected system, no point overdeveloping just few main parts for the show or mirror look, rather work on everything.
