Actually, most of the Gene Tonics are more skewed that the Fountain of Youth -- they give advantages to the player without any disadvantage or neccessery extra effort to using them. Shall I give examples? Armored Shell, EVE Saver, almost all Engineering-type Tonic, Arms Race, the elemental immunity-Tonics, Demanding Father, the research Tonics, Sport Boost and its companion, Security Evasion... These Tonics do not demand any price or extra action for their use over the player's usual activity within the game. On the contrary, the FoY do this, in a certain negative sense: the player stand still for extened periods of time, what he/she wouldn't do without the Tonic. As I said, this is the "price" of using this Tonic.

And please, do not declare that your tweaked version would be better than the original, because exactly this is the question our debate is about.
