Rereading an old diary, I found a rainy season entry where I was lamenting the smelly fact that many farang refused to shower because it was too cold. Most were guys. Dunno if this still happens, but it drove me nigh on crazy. This was before hot showers in my village. But five minutes of "refeshing" cold water clean was lovely to me.
And how about some deodorant? I used son sam (rock salt), coz it's dead cheap (Bt15 a kilo maybe?), works well, does not stain and does not irritate skin. Not an anti-perspirant, tho, but I had maybe five showers a day when it was hot.
