Man showering feels sooooo nice. I have to wonder, did we evolve to feel this way or did the first prehistoric human to use soap and water feel this good.
@freemo Evolutionary response to life-giving rain, perhaps?
@louis I had thought about that.. but i dunno about you when i stand in the rain i feel the opposite of when i shower.. i feel more dirty and sticky and itchy, not less. Same for a clean pool. This seems to be a response unique to soap and water specifically. Keep in mind though we invented soap a very very long time ago in oen form or another. It started as natural soap occurring in lye rich rivers that people discovered and started using for cleaning.
Are you talking actually being in rain without an umbrrella, oe simply just being outside in a dry place while it rains around you?
@freemo Yeah, the former. Sometimes when I'm home and it rains, I'll just go outside and stand in it for a while for fun. Usually not to the point of being soaked, and I change clothes as soon as I get back inside, but it feels nice.
@louis I do enjoy walking int he rain, its a good expiernce. But it doesnt make me feel clean like a shower does, in fact it specifically makes me feel like i need to take a shower.
so after you are done with the rain you have that clean feeling you feel after taking a shower? Weird.
@freemo I wouldn't say it makes me feel clean (although it doesn't make me feel less clean either). I'd describe it as "refreshed".
For reference:
Rain: not cleaning, but refreshing
Shower: cleaning and refreshing
Sponge bath: cleaning, but not refreshing
@louis Yea I can get with the refreshing part.. though it does make me feel less clean.
@freemo Ah, then you and I have very different responses to rain. For me, it's rejuvenating even when it's whipping and cold.
But especially the idea of a gentle warm front blowing in and raining after a long dusty day working in the hot sun is exactly the same feeling I associate with showering after getting grimy in other ways.
