Prohibitation for mixing meat & milk, Biblical?

[Dawid]

Heard that sleeping on a hard bed helps. I really think a gym is a good idea, help the blood circulate in your body, fresh oxygen, keep your muscles in shape, so forth. Going to give it a try (it helps your exam performance according to what I read in some papers as well).

It definitely does. I had a soft bed until recently and waking up always hurt. We replaced my matress and it's a lot better now.
Cool. Sounds like a good idea. Have you tried swimming?
