bigger, stronger, magnets might be more annoying day-to-day simply because finding yourself accidentally picking up silverware and stuff can be uncomfortable, but this shouldn't be dangerous as long as you are a bit careful.
that being said, I have woken up with my finger stuck to my iron bedframe, and was in pain for quite a bit afterwards. in extreme cases, this sort of thing can severely damage the skin over the magnet and cause irritation/rejection. but all that is still more of an annoyance than an actual danger to life or limb.
