Its so difficult to judge what is enough and what isn't. Mika is definitely pushing himself/being pushed to certain limits...this has happened with several newcomers, in particular James Morrison. He ended up canceling his entire Asian Tour along with some European gigs. He kept falling ill with throat infections etc and was being run down. It'd be such a shame to see this happen with Mika, but unfortunately time waits for no-one. When there's a window of opportunity you just have to take it while you can, hopefully Mika and his management know the limits and won't let him burn out...
I along with others, will be awfully disappointed if Mika happened to cancel any gigs that I had planned to go to- but that's all it is disappointment- it pails in comparison to ill health.
Keep well and take care of yourself Mika:original:
