Prohibitation for mixing meat & milk, Biblical?

[Dawid]

I'm 25 myself. Ahem...not too old, but I feel really old. Went to the Doctor to check for some Asthma some time ago, not too well. Better go to a gym or something to try to fix my health, especially since my own father is aging way too quickly in my opinion. I even have some white hairs in my head, do you believe that?

I know the feeling. I already have back trouble sometimes.
