Prohibitation for mixing meat & milk, Biblical?

[Dawid]

That's sad bro, I still want to do some swimming when possible, it makes me feel brand new. Cardio....maybe some 15 minutes then endurance training. Just to feel a little healthy, then I'll give the pool a try when it starts working again in our building (they are cleaning it up or whatever). If it continues this way, I'll wait until spring for the public pool.

Oh, I'm not knocking swimming. It's great. Just make sure you do it right. I was on team and my coaches didn't even correct what I was doing, and I ended up messing myself up.
Cool.
How did we get to swimming and exercise from mixing meat and dairy? lol.
