I'm studying at a univetsity and I want to begin to do sports. I want to do kickboxing, but I'm afaraid of to get strong hand blow to head bucause due to it I can get concussion of the brain which may cause my mental abilities to deteriorate. I don't want it because I also want to become a good programmer, but because of this, the chances of becoming a good programmer will be much less.
I need to be strong to protect people close to me. I really can't live in peace having a thought that if my people need protect I will not be able to provide it to them. I don't want to be a weak man, but I also don't want to be a stupid man.
Pls, gimme an advisement.
I agree with the sentiment of the other posts - you're over thinking it.
All martial arts come with an inherent risk of injury, some more than others but once you start, one of the fundamental things you learn is restraint and control. General sparring/training won't be too rough on you unless you get an asshole partner or you're still not prepared enough. If you're afraid of taking blows to the head then look for one that's less heavy on the head like grappling for example.
Try to find a physical hobby that you enjoy and improve yourself through that. Try out a couple different stuff and stick with one that resonates with you the most. Make some friends, expand your worldview, learn new things - you'll get further in terms of strength and skill if you're actually into whatever you're doing.
Also, it doesn't have to be a fighting sport. Any sport or physical activity will make you stronger. If fighting ability is what you're after then go for it, but it's not the only option.
My advice is that fighting isn't the only thing when it comes to protecting your family. Physical/mental health, knowledge, finances, reliability, sociability; a lot of other things are important as well and deserve the time to be worked on.
