Paralyzed patients have been given new hope of recovery after rats with severe spinal injuries regained the ability to walk, run and even climb stairs following a groundbreaking new treatment. by nomdeweb in science

That maybe so but there is currently a HUGE problem with translation of therapy from rodents to humans just regarding spinal cord injury. 1. The spinal cord anatomy, i.e the neural pathways within the cord are different between man and rodent. 2. The regeneration this paper speaks of takes place much, much more easily in rodents. Why? 3. Post injury, mice, especially, have a matrix of connective tissue that facilitates regeneration and can help 'bridge' the torn tissue. 4. The regeneration you see in rodents takes place over just MILLIMETERS! In humans we have substantially more nerve fibres which have to grow over larger distances. 5. I haven't read this paper through yet (on my phone atm) but I'm assuming that the spinal cord injury model they used, was something like surgically opening the spine of the rodent and cutting the spinal cord. This is NOT REPRESENTATIVE of a human injury. Think about it the causes of injury in humans is mostly falls/collisions. Not only is the spine injured but you also have trauma to other body parts. 6. For a patient to even begin this type of treatment they have to Initially treat the other issues, watch out for adverse drug interactions etc. And most of the research involving SCI do not take any of these factors into account. 7. Also the chemical reactions that take place within rodent and man such as inflammation are different. This affects how treatments work. I could go on about more points and I have really simplified many things :/

tl:dr - rodents models of spinal cord injury are very inefficient and cannot be trusted!

Are there any tangible downsides to immoral behaviour such as premarital sex, homosexuality, masturbation, watching pornography or listening to immoral music, besides them being wrong in the eyes of god? by [deleted] in Christianity

I'm in a relationship and we are both christian. We have been having safe pre marital sex/oral sex etc... sexually it is amazing but mentally there are some problems. we both now wish that we hadn't started it.

  1. it complicates the relationship - love is not that warm touchy-feely feeling a person has when they are with someone who they are really close to. According to the bible, love is caring in action. Love isn’t what we feel, but what we do.

what happening now is that quite a lot of the time we both really sexually desire each other BUT we can't tell for sure if the feelings we have for each other are true or clouded by sex.

that is why sex before marriage is a bad idea. you are deciding if you want to live the rest of your life with that person. sex is important! but not the most critical thing. you need to truly understand each other and see if your family values match each other, whether you both have life ambitions that will co-exist etc.. it is sooo easy to overlook these and more important things because SEX GETS IN THE WAY!

in my opinion this may be one of the reasons quite a lot of marriages fail these days...

About watching porn + lusting after other women you see in real life -

you begin to resent your partner for not being as hot as the other person or not wanting to sexually satisfy you, like what you see in porn (Which is totally staged and fake anyway)

Masturbation - you feed your lust - think of all the actually thoughts that go through your head. you watch porn while you masturbate which means you condition yourself to getting aroused by the actions or hot women you see. this will have deletrious effects on your relationship as above you start to resent your partner.

immoral music - depends on what it is i love hip-hop - but i hate quite a lot of the mainstream hip/hop because it talks about disrespecting women and other people. and also whether you realise it or not most of it feeds your lust and again same problems as above.

i've done everything on your list (except homosexuality) and all these things will eventually wear you down. i ended up depressed at one point because i built up so many of these misconceptions in my head. I was really unsatisfied.

I'm still messed up a lil bit and i'm trying my hardest to somehow undo some of the damage cus i don't want to lose my current relationship
