Those low testosterone commercials you see during football games and other manly TV events are kinda bullshit. Everybody gets old. You get weak and soft, you don't want to play sports anymore and your dick doesn't work so hot. That's why God invented whiskey. Just pour yourself a glass and enjoy the long slide down. You earned it, pal.*
*If you don't feel like you earned it though maybe you should give yourself a shot of testosterone and try agin you little pussy.
