So, lemme get this right - unless you know the water temperature, you can't tell how old they are? Like, in the first one they are 480 degree days old. As we don't know the water temp they could be 48 days (@10 degrees) or 80 days old (@6 degrees).....? And what happens if the temp changes, like for half the time it's 8 degress? that would make them 70 days old.... ehhh? Blimey, the Gregorian calender DOES have it's advantages ;-0 Wow. poor things. imagine not knowing when your birthday is coz it got warmer........ (",)
