You talking about the kenna cook on the inside one izzit?
That one is super urban legend lor. Yes, UV lights will make you
suffer sun burn, you may scream here scream there for a few days.
But cook you on the inside? No. Because UV lights are very
different from microwaves, so even if you want to be cooked by the
tanning machine, u lay down there for 1 whole day also won't kenna
cooked one.
