Don' they clog up your lymph system? I don't use them personly, I dont react well with them, I just shower every morning and afternoon, and use cologne if I wanna smell good...
Just a quick science bit, I think- correct me if I'm wrong- sweat contains pheremones that attract women so long as its unter 24 hours old. After then bacteria starts to get to it and u smell like poo. Which is never good. I'm not saying thats an excuse to get all sweaty, and I definetly wouldn't buy any of that pheremone sh1t, but I'd use it as an excuse to avoid the sprays and just wash.
Hope that helps in some way
