EPIRB...Yes they do conduct a colour vision test. From what I have heard they do like you to fall into their Height/Weight range. I am not sure if they look at BMI specifically.
As Kaptin M said, the blood test basically covers everything, didn't have the time to write them all.
Would'nt it be a good idea to go for a blood test and get the works to see if anything was out of the norm, and try and put it right!!! Say cholesteral for example.
2XL...re your allowance question...sorry I dont understand?
