How do you know he was a creature of habit?
I hope someone who reads about his death will realize how easy it is to drown and will take lifesaving precautions, especially when alone in the water. Knowing how to swim does not mean you can survive cold water shock, or swim when wearing heavy clothes/shoes. Thinking you cannot capsize in a canoe, don't need a life jacket or will be able to grab onto the canoe/boat are deadly mistakes.
What a terrible loss of life, we lost an 18-year-old too, it's just devasting.
