I believe that hapiness lies first of all in health.
In my opions ,health is more important than every thing.You can't do any thing except of sleeping,if you are ill.For example you can't play basketball ,you can't play football and so on!However,now the best fair-sounding music goes with you,I don't think it can catch your ears.
If the health is away from you ,you must will miss many many nice things!I don't think you are happy when that is happened!So health is the basic of happiness!
So we can happiness lies first of all in health!
