cut them off or leave them alone?

hi everyone. just a quick question. some of my lower leaves have turned yellow and are dieing off. should i just let them shrivel up and drop off by them selfs or should i cut them off? thanks

i just pull off the dead yellowing leaves when needed, and they do just fine

id take them off if they are dieing

ok thanks peeps. as for my fan, should i have it so its still and blowing or so it moves left to right? thanks
