Laughing all day long has some cardiovascular attraction to it, I think it falls safely within the “too much of a good thing harms” truism construct.

It can cause disruption to one’s social network as those around you alternatingly attempt to assist you and silence you for reasons of self-preservation. It can confuse your companion animals (provided they are mammalian, like cats or dogs) and may trigger law enforcement intervention during sojourns outside of the workplace or home.

Physical affection would certainly be curtailed as well, since embracing another person while laughing loudly can cause ear damage to the huggee.

I suppose proper pacing could reduce the adverse affects, and scaling the laughter to an occasional chuckle through a s**t-eating grin may, indeed, be a wholly superior option.

Do whatever, I guess; but I, for one, will just smile enigmatically.
