Your solution is partly right.First, what will you do if there is no fridge in your car and you can not eat so much chocolate?for example, you have had breakfast yet. Second,if we are eatting only chocolate all day our body will have to absorb preservatives and what about healthy diet? Would it be good for your teeth,hair and so on!?
third,some can not eat chocolate cause of the reaction,in this case their body is started to itch,they prone to allergical problems.I think that chocolate is important but you should eat a definite amount of it and keep your weight uder control.
