There are a lot of benefits to summertime. We've got a whole lot more sunlight, the weather is agreeable and taking half days on Fridays is a whole lot easier. The downside is that good times can quickly become awkward or uncomfortable when you get a whiff of your own B.O. Then, suddenly you're self-conscious. And it's not like you're not trying. You shower in the morning, you spray on some cologne before you leave but by lunch, you can feel like a sweaty, smelly beast. Is there anything a guy can do? Actually there is. This is all about biology and chemistry, so using some science to combat the problem is the solution to a stink-free summer.
