I wanna go tanning so bad, but I'm too scared!! I already have a heart problem going on I don't want to risk getting skin cancer too. I'll settle for spray tans but not sure if I should do a tanning bed or not. I have a pacemaker and people I know have tanned with them and everything was fine, any advice on what I should do?
