you raised an excellent point bro a lot of artists died and are still dying because of refusing to respect rest,three reasons behind it,first they are too addicted to their job you can find even jb for example go on 8 months of concert in kin 4 concert every week with a poor voice because of his health instead of going to his doctor in france and face the rest he has to get even if its a year,then you have the very fragile social condition of musicians,they can go from everything to nothing in a blink of an eye,especially band members so playing through pain maintains the bare minimum to take care of their families,and the last one is shame,they hate being seen in a position of weakness,i think even late seguin would be upset if he was aware of kanza's leaks to reassure people before the bad news really happened
