Hey Old Dude...
I appreciate the candid answers. You have outstanding cred with all of the evacs you have been through.
Let me summarize what key points you bring to the table here:
1. Advance Prep for larger loads and tasks
2. Recruitment of Help for moving large loads
3. Performing heavy tasks carefully/slowly within your physical limits.

Thanks Old Dude..
I think that lines up with assessing tasks in relation to fitness pretty well.
