I find it funny that these days if 'scientists' can't seem to find irrefutable evidence of something, then humans are either too lazy or too incapable of believing something. Yet there are so many who, to this day, believe in the existence of a god of some kind.
I've always thought that attraction has a lot to do, (if not everything to do) with pheromones. It's the reason that no matter what kind of a 'type' a person is interested in, sub-consciously they may be turned on or attracted to something much different. It's why sex with some people can be so much better than with others, and why there can be a complete lack of stress or physical fault with some, regardless of experience, and an utter disaster with others.
In nature, animal breeding is all about pheromones. Why is it so hard to believe that it would be any different for humans? Just because some scientists cannot understand or measure exactly what attracts what and how they work?
The point is, while it may not make you a total chick magnet, and the media often tries to play the 'pheromone' word as some sort of a selling point or gimmick, I think the real answer is that sexual attraction, a change of blood pressure and many other things are attributed all to pheromones.
Putting all of this aside, celery is actually one vegetable that doesn't taste like trash and is incredibly easy to eat due to it having an actual solid fibre body, while still being mostly comprised of water. In addition to that, one can eat a lot and supercharge the body full of all the nutrients and vitamins that it contains without feeling sick. Vegetables like capsicum, lettuce and cauliflower, while also equally good for you, are either unable to be eaten easily in an unprocessed form, or still require a lot of trouble to prepare.
Even if you don't believe in the whole pheromone side of celery, you should eat it for the circulatory benefits and sexual benefits. A lot of people eat celery religiously before going out to bars or clubs. It also helps counter the effects that alcohol has on suppressing the sex drive, as well as the ability to get an erection. It won't stop you from getting drunk, but it will allow your body to be a lot more 'forgiving' so perhaps you won't embarrass yourself when it comes down to doing the deed.
My advice to everyone is to not discredit something just because scientists don't have sufficient evidence, or there isn't concrete proof.
