The only reason that some religions forbid gambling is because it’s very easy for some people to get addicted and to lose everything and destroy their lives or worse, their families. Not everybody has an addictive personality and plenty of people are capable of controlling their gambling and restricting it to only what they can afford to lose.

Moreover, when playing “gambling” games like poker, or really anything, if there isn’t any actual money or stakes involved (e.g., playing with chips for fun), then there is no harm in it and it’s perfectly fine for everyone to play, young or old, without fear of going to Hell (the only problem then might be sore losers who get angry and rage, but they’d probably do that over anything that sets them off).

The reason that religions forbid gambling is because it’s easier to make blanket laws that apply to everyone, including those that it doesn’t even apply to. This is particularly true of religious laws from a long time ago when people were a lot more simple and education was limited to just the elite, so most people couldn’t understand more advanced reasoning like psychology and germ-theory. I’d like to think that we’re past the point of hand-holding and can be trusted to understand the reasons for rules and commandments and laws can be more specific to the individual person and circumstance. Unfortunately, there are still far too many stupid people, and worse, the human population just keeps going up at an accelerating rate, which makes it impossible to deal with things individually, so we still need blanket laws. 🤦

Some religions (notably Islam) mandate that people perform ablutions before praying. During the prayer, it is also required to stand, kneel, bow, and prostrate several times.

Washing makes sense because back in those days, bacteria and viruses were neither known, nor could be understood by the average person. They had no microscopes, so convincing people of invisible creatures that surround us that can harm us was a difficult task at best. It was much easier to just require people to wash as part of the prayer to keep people sanitary. And since most of the people where these religions began lived in desert areas, washing not only was a way of ridding people of germs, but also cleaning off the sand that invariably gets into their nooks and crannies. Moreover, requiring them to pray several times a day, keeps them clean all day long.

The physical movements involved with the prayers also make sense. While some members of society would get plenty of exercise from hunting or farming, there were still plenty of people who remained behind and could get out of shape. Requiring people to repeat some simple but muscle-using movements several times a day was an effective way of keeping the populace physically fit.

Granted it would be ideal if one could just explain things to do to keep a person healthy instead of having to trick them, but back then it was pretty difficult (just look at how well it worked out for so many prophets and scientists). Besides, today we do teach people things to keep them healthy and nobody listens. Maybe parents should take a cue from the past and find a way to trick their kids into eating healthy, exercising, and washing.
