So, you've been dropped by people having only:
1. One leg
2. One lung
Now there's something to tell your grandchildren!

Seriously though, I really don't care if I'm being dropped. I know I'm in pretty poor shape, so I don't feel bad about it. I'm pretty sure your average fit 12-year-old could drop me on an MTB with knobbies. I'm that bad.

A guy in my club is 67 years old, started cycling less than two years ago, after an entire life of inactivity, and he has no trouble keeping up with most of the young guys in the club. In two years time, I know I won't even be close to his performance level, even if I followed the best possible training schedule.

You'd think, then, that I'm the endurance type instead...
WRONG! I suck at that too. My longest distance, so far, was 154 km (96 miles), and the last 30-40 km were covered going veeery slow, and in pure agony. Average speed was a poor 24 km/h (15 mph).

My guess is that 80-90% of the population has greater potential than me, when it comes to cycling.
