  • To piggyback on another comment. Massage. I’m a massage therapist who sees clients with disk issues all the time.

    99% of the time it’s because of shortened hip flexors (your psoas attached to your bottom vertebrae and as it shortens, is too tight to let your spine stretch which then just crushes your disks) due to both extended time in a seated position as well as a weak core. Stretch, get a massage, find a PT to help with chronic back pain. Start doing crunches before bed.

    Also drink more water. Only kinda related but basically everyone should be drinking more water.






  • Yea, the evolution of vascularity in plants let them get off the ground in the first place (meaning being taller than a few inches). Vascularity is the first big jump plants made after leaving the water. From there, being taller means outcompeting your neighbors and spreading your babies further. When you have that double whammy of more food + more babies, you get a selective pressure for taller that never really goes away. This is why multiple families have species that have arborized and have continuously done so over their evolutionary history. If the niche is empty, something will jump into it, often sooner rather than later (on a deep time scale) which is basically the whole idea of convergent evolution as a whole.

    I wasn’t being specific enough. Cell walls in plants are composed of cellulose, hemicellulose, and lignin. Lignin IS one of the structural polymers that plants produce, and yea, every single vascular plant has and uses lignin to provide structure. Iirc its a polymer produced by every plant, including mosses and other nonvascular plants, it’s just not used to the same extent.



  • Animals are members of kingdom Animalia. One of the unify features of this kingdom is multicellularity. Slime molds are members of the mostly-single-celled protists and they themselves are some of the most complex single celled organisms. Sponges, being very basal animals, are one of the phyla that retains a high degree of regenerative ability that simplicity facilitates while being very much a multicellular organism with all the organization that comes with.
