It’s not about the surface area, a tear heals without creating a straight line of inflexible scar tissue in flexible tissue. You recover faster and better, because you distribute the new connections throughout the tissue, you don’t have this one rigid perforation to tear, so you don’t have to be healed up all the way before you can get back on your feet

In general, it’s the opposite though - a sharp cut heals much faster than a rip, there’s far less damage to repair

Thanks for the explanation!

Isn't this a function of the surface area, though?

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
