You crashed as little kid and lost a tooth? Wow! Hopefully it was a milk tooth. I understand that you don't like racing after that incident, but if you push yourself to do it then you'll get used to it again and love it. If you use full face helmet you are well protected.
Have you not seen the insane accidents in formula 1? The cars are sometimes reduced to fragments but they often walk away from it with no serious injures. Only a few accidents are serious.
As gold member you can not see invisible staff, I remember that from the time I was just gold member.
If I log off now, you'll still not see when my last activity date was. It's disabled until I uncheck the invisibility in my account settings. Nothing is hidden from other staff members though.
You can see for yourself by going to Angels account, she's always invisible. She's not online now, and you'll probably not see any 'last activity' data. I will see the data though. She's in my friends list if you want to find her account.
Btw, there are no invisible gold members online a.t.m, they've signed off.
