I mean…sort of? I can’t say that’s wrong, but I also don’t think it’s the full picture

Like imagine a cut rope. Gluing the ends together joins it with a weak point, but if you unravel the ends and weave them back together, you can create a very strong connection, even without glue

Yes, the surface area in the latter is far greater, but in addition to the surface area you have the structure - the weave itself grants strength, because when you pull the rope the fibers compress against each other, making it stronger than just surface area contact

I think it’s kinda like that, surface area certainly plays a big part, but I think it’s more than that. It lets the muscles reweave themselves - as opposed to the skin and the uterus lining, which are cut in straight lines to minimize damaged surface area - they’re more like cloth than rope, you stitch them up in neat lines
