All i do in a day is play Guitar or Moderate here.. Build sites. and stuff..
But i've never had health issues.. Especially with fingers cause i never have played on rusted , old strings. So i never had calouses and cuts etc..
I wash my hand s with dettol like two times before and afte rplaying.. I guess thats like the best i can do.. But most musicians i know practice more than me.. So none of them have problems..
