If you're just depressed and feeling alone, think about the people who are really suffering with non-stop excruciating physical pain. Your sadness doesn't mean shit to them. This thread is actually extremely offensive to those people. If you're healthy enough to frontside flip of a bridge, you're healthy enough to live. Quit being a bitch.
I think OP means this is a thought experiment, not as a reality. As I said in my reply, even as a fifth grader, I thought it would be a great way to go out.
In reality, we will all die of old age, illness or disease, acts of god, substance abuse, or something else unknown to us at present.
Just have a good time skating around while you still can. Every day you have mobility is a great day.
